Why Lada Priora starts and stalls and what to do

1. Hello people. Help, the engine of the Priora 126 starts up cold and immediately turns off, you have to suffocate, what is the reason? How does it heat up - everything becomes normal. Question: Alexander Sergeevich 2. Hello everyone. Here’s the problem: when the Lada Kalina 8 cl engine is running, the whistle whistles like on the remote control, like on a running turbine, and when you turn on the gas, the whistle gets even louder. Question from: Nikolay Kucherov. The Priority starts and immediately freezes when cold.

Do you have a precedent with an electron accelerator?

The filter has nothing to do with it. Just when the engine warms up, the oxygen sensor turns on, which adjusts the air-fuel mixture. Therefore, it is necessary to inspect the mass air flow sensor, the throttle valve and everything connected to it. Try to stretch all the joints of the suction system (pipes). Clean the throttle valve. Therefore, it is better to make a diagnosis.

Victor, no cable

Alexander, if it’s a cable, check the TPS (throttle position sensor). If the needle on the speedometer jumps, then it’s safe. If you are familiar with the same engine, you can simply ask to transfer these sensors from its engines to yours for a while. This will be cheaper than buying and checking by typing. But even better for a regular diagnostician.

During the operation of a car, it is not uncommon that after turning the ignition key the car starts, the engine starts and stops after a few seconds. As a rule, 3-5 seconds pass from the moment of starting to stopping the internal combustion engine. Before the engine stops completely, engine vibrations are also observed, the power unit shakes, and is very unstable.

This is due to speed reduction, resonance effect of the rotating crankshaft, etc. If you try to restart the engine, the engine may not start or the above situation may occur again.

The reasons for this problem are different. The main thing is that if the car starts and stops, this indicates that a thorough diagnosis is required. Next we will talk about what to do in such a situation and how to find the reason why the engine stalls after starting.

What could it be?

Causes

Your car may not start right away or may stall immediately when one or more parts of the system are faulty.

Now let's look at the reasons why the Priora does not start at all. So:

• Check the electrical connections of the ignition coil. They may be weakened or damaged. Replace if necessary;
• It's also worth taking a look at the fuel rail. There may be insufficient pressure;
• there may be problems with the intake tract. Check the catalytic manifold and intake manifold. The connections of these parts may be leaky;
• Perform engine diagnostics. It may be broken;
• oil can freeze in the cold;
• The battery may be low. This can be understood by the rotation of the crankshaft;
• an equally significant reason may be frozen water in the ramp, in which case your fuel system is faulty;
• in the cylinders - low pressure;
• It’s also worth checking the fuel injectors, they should be sealed;
• Possible injector malfunction.

Your favorite car, Lada Priora, may have difficulty starting during frosts, that is, it will start and immediately stall.

There are also a number of reasons that cause this problem:

• large accumulation of water in gasoline. Check this and better change the fuel;
• examine the entire ignition system - from the module to the high-voltage wires;
• look at the oxygen sensor;
• Another common cause is a malfunction of the immobilizer and alarm system. Many people advise solving this problem by reflashing the engine control unit.

Equally important is the constant maintenance of your car.

It may be that the starter turns, but your Priora does not start. What can be done about this?

Fuel pump

This is one of the popular reasons why Priora has difficulty starting when cold. This is due to a malfunction in the fuel pump. You can even hear the sound of the node operating. But if the pump is faulty, the fuel system will not have the pressure necessary for normal operation. There is no pressure in the fuel rail, which means that starting will be poor, or the engine will not start at all.

The fuel pump can only be checked using your ears. You need to turn on the ignition of the Lada Priora. At the same time, if the fuel pump is working, a characteristic buzzing sound will be heard from the side of the tank. It will only last a few seconds. When a sufficient amount of gasoline is pumped into the ramp and the pressure becomes normal, then the pump will turn off. If there is no buzzing sound after turning on the ignition, it is recommended to replace the fuel pump.

Causes of management problems

The Priora most often does not start because the battery drains quickly or is completely discharged. In this case, the amount of charge is not enough to operate the engine.

Diagnosing the starter is easy. To understand what condition it is in, you need to pay attention to the sound coming from under the hood. A cracking sound will indicate a discharged battery. Charge the battery. Any parts of the car may be subject to corrosion, which will subsequently weaken the contact between them.

Humid air also affects parts, and if your Priora has a full gas tank and the battery is charged, pay attention to the following:

• starter;
• battery terminals;
• connections between the wires of the circuit;
• presence of condensation.

In case of corrosion, clean or replace the oxidized element. The terminals still need to be coated with special technical Vaseline. For the system to work, pay attention to the position and contacts between the wires. If at least one is disconnected, connect according to a special diagram.

Use a tester to check the condition of the coil. Check the fuel pump relay and fuse. It may be damaged and interfere with the fuel supply.

Replacing the gas pedal on Grant

The replacement procedure is quite simple and does not require special technical means. In order to dismantle the unit you will need: - A key for 10.

Sequential steps to replace the gas pedal of a Lada Granta:

1. The first step is to remove the negative terminal from the battery. 2. Next, you need to move to the driver’s side of the car. 3. Above the gas pedal, find and disconnect the contact chip that is connected to the sensor connector.

4. After that, take a 10mm wrench and unscrew the three fastening nuts. When there is insufficient internal space, it is most convenient to use a socket wrench. 5. Remove the pedal from the special mounting pins. Reinstallation is carried out in a mirror sequence.

Checking the operation of systems

If the starter turns, but the Priora does not start, pay attention to other systems. For example, the power unit cannot start working if the ECU or coolant sensor is faulty.

If the crankshaft sensor stops working, then you need to immediately contact professionals at a service station, but, alas, you won’t be able to get there; you’ll have to call a tow truck.

Problems with the crankshaft may be due to the breakdown of individual components of the cylinder-piston group, generator wedge or coolant pump.

During frosts, oil can also freeze. In this case, drain it and switch to the one recommended by the manufacturer.

The engine may not start if the fuel line or fuel line is not working properly. They may be dirty or damaged. But despite all this, the starter can work normally. Clean the wire from dirt to restore pressure in the rail or completely replace the damaged areas.

An equally important reason that the Priora does not start may be a blown fuse, control system relay or idle air regulator. Try pressing on the gas pedal until you accelerate. If, after you release the gas pedal, the Priora stalls, then this is a problem with the idle speed sensor. Contact the service station.

All these problems are very serious and require immediate repair. Be sure to diagnose all systems so that you do not return to this problem in the future.

Why does the engine stall when it is hot, and a well-warmed engine does not start?

1. The first possible reason is the carburetor. During movement, a large amount of air passes through it, due to which the carburetor is seriously cooled, at the same time the fuel that passes through it is also cooled. As a result, the carburetor temperature is several times lower than the engine temperature. Because of this feature, problems arise; after a long journey, you turn off the engine and make a short stop, at which time the carburetor begins to get very hot from the hot engine body. The remaining gasoline in the float chamber begins to evaporate from the high temperature, filling the voids - the air filter, the intake manifold and the carburetor itself. Air pockets form, and not a drop of fuel remains in the float chamber.

The solution to the problem is quite simple - press the gas pedal halfway several times and try to start the engine. This will make the mixture leaner and release excess evaporation. It should be noted that problems with hot starting can also be due to a similar problem, only due to the fault of the fuel pump or fuel line. This usually happens in hot weather when air pockets form from evaporation in the fuel system or pump, preventing fuel from entering the carburetor.

2. The second possible reason for the strange behavior of a warm engine is problems with the starter. Make sure that when you try to start the engine, the starter turns and does not just click or not respond at all. If this is the case and one of the above options is confirmed. the starter needs to be checked. If you are on the road, then the check can be reduced to a basic check of the starter power wire or other visual operations. If you get home, perform a detailed check of the starter according to these instructions. In case of malfunction, repair or replace it.

3. Alternatively, the reason when the engine does not start when hot may be a dead battery due to the reason described above, when the generator did not charge and the battery was completely dead.

Well, it seems like you didn’t miss anything!? That's all for today, we hope the article will help, tell you the cause of the breakdown and help you solve your problem.

Checking the exhaust system

It may be that your beloved Priora does not start due to a poor air-fuel mixture. The engine may stall if the exhaust gases are not removed but mixed with oxygen. In this case, there are only two reasons for the malfunction:

1. Malfunction of the muffler catalyst. This may be due to debris and dirt in it, and in frosty conditions the liquid contained in it can freeze.
2. The muffler itself sometimes freezes up due to the liquid in it, or it simply becomes clogged with debris.

Engine power system

A big role in determining the reason why the engine stalled is the diagnosis of the engine power system. At the moment, gasoline engines use two different components of the vehicle power system:

• carburetor
• injector

In an injection engine, problems are mainly associated with various sensors. Replacing the sensors one by one allows you to identify and eliminate the problem.

In the case of a carburetor, the engine may stall both at idle and when increasing/decreasing speed.

The main reason lies in debris that can clog the jet in the carburetor. Blowing, cleaning, and using special aerosols can eliminate this problem. To prevent the situation from reoccurring, it is necessary to change the fuel filter. It is also necessary to inspect the pipes. If they are old, then they need to be replaced, since particles flying off from them can constantly cause problems with the carburetor.

Checking the ECU malfunction

This check is simply necessary, since ECU breakdowns are very common. This is the main reason if your Priora starts and stalls after a couple of moments. Some damage can be seen on the control panel. For diagnostics, you need a special device to detect errors.

If you are unable to solve this problem on your own, contact a specialist.

The fuel pump screen is clogged

For cars of the VAZ family with an installed injector instead of a carburetor, it is typical that the car starts and stalls. Sometimes the reasons for the engine stopping on its own are due to a malfunction of the fuel pump. If the car stalls immediately after starting, but then starts, the problem lies in a clogged fuel pump cleaning screen. In this case, you need to replace the mesh with a new one and enjoy the further movement of the car.

In other cases, it happens that the car starts perfectly when cold and does not even stall, but as soon as it warms up or at hot temperatures outside, it begins to twitch. What is the problem if the engine starts and stalls when cold? It is hidden in the performance of the fuel pump. Sometimes such signs are characteristic of poor fuel quality. This is also caused by a clogged pump screen.

Communities › Lada Priora Club › Blog › Starts and stalls…

Friends and comrades, help me out, I no longer have the strength to fight this accursed woman. The situation is this: I start the car mainly from autostart. At the moment of starting it starts and stalls, it takes 4-5 attempts to start. Moreover, at night I have it for about 8 hours and starts 4-5 times, I come to work - it sits there for 12 hours and starts the second time. It happens that it won’t start with the key, but if at the moment when the current grabs you press the gas, it won’t stall. I changed the idle speed control, the throttle position sensor, the spark plugs, the injectors, the knock sensor, but there are no errors. Maybe someone had such parsley, help me out, otherwise I’m afraid in the cold I’ll just put the battery in with so many starts.

Oil

Many car owners try to change their oil before winter. But not everyone knows that the oil with the lowest viscosity is best suited for winter. Thick oil will simply harden in winter. In addition, when the engine is cold, it is very difficult for it to drive thick oil through the channels. If the picture is complemented by an old battery, then this aggravates the situation even more. Therefore, you need to try to purchase oil of exactly the viscosity at which the engine can start normally even in cold weather. Typically, a product with a viscosity of 5W30 is purchased. But in any case, you need to look at the manufacturer's recommendations. You should not deviate significantly from the tolerances.

wash the throttle body!

found the reason? same problem

no, I haven’t found it, I want to find a real IAC, not a fake one, but I can’t find it yet

I found the reason, look in the blog tomorrow, maybe it’s the same for you

it's good if I found it, I'll definitely read it, I hope it's the same for me

In short, I realized one thing in car services they screw up, it’s better to look for those who do diagnostics at home themselves, but in general someone in our city should know good diagnosticians; you can count them on the fingers of one hand, I think in your city you should also ask your friends

check the pressure on the ramp, if the current with gas starts up, then the rcx is to blame, because it is he who sets the starting gap bypassing the damper. Rhx is the nose, and the throttle is the mouth, close both and there will be nothing to breathe)). Well, look at the dpkv again, maybe the wiring has come loose

Lada Priora Hatchback › Logbook › Starts up and immediately stalls

I'm changing the IAC, it doesn't help, I'm going to the diagnostics on a hot one, of course there's nothing there, it doesn't show anything, everything seems to be fine. Well, great, I think I’m going to another diagnostic, and it also says everything is fine, but I need to look at it cold. I drag the car to him on a cable and he tells me that at the moment of tripling it begins to misfire in all cylinders in turn, I need an IAC sensor, I don’t have enough air for her, I change it, there are no changes, he says let’s flash it, maybe with the program we’ll flash something all the same. I am changing the fuel pump because this one gave 3.5 pressure, the new one gives 4+ pressure and still no changes, I tried installing all the coils and sensors from another working machine and still no changes.

Hurray I did it! When it was left to try to replace the only camshaft sensor, then I started removing the intake to change it, otherwise I wouldn’t be able to get to it. I installed a new sensor and put everything back together, but it got worse. I started disassembling all this garbage again, installed the old sensor and noticed that the rubber bands on the intake manifold were completely dry. I went to the store and bought rubber bands for 80 rubles. I assembled everything and the car froze. Well, I think I’ll try it in the morning when it’s cold, I go out in the morning and here it’s -28, I sat down and the car started and didn’t stall for three days, everything’s been okay. The result of this event is almost 7,000 rubles, which were spent on sensors, diagnostics, and a fuel pump.

Hello guys! Who is watching knows - the car is after an accident! I bought a new ABK! The problem is this: I insert the key, turn it, everything lights up, the fuel pump works, I start it and it just starts and immediately stalls! There is no time to react to the gas pedal! Where to dig? what could be the problem ?!

Once again I need your help! Anyone who has encountered this, TELL ME!

My friend, tell me, what was the reason? why did she go deaf?

Salute, during an accident the intake manifold was punctured!

Thank you very much for your prompt response! I didn’t have an accident, I’ll check the IAC tomorrow.

My pleasure ! ))) his first thing! Air is being sucked in somewhere...

There is no need to guess, but you need to go for diagnostics - so that they connect the device and see if there are any error codes. I had such a problem, I replaced a bunch of sensors according to the advice from the hot weather (both IAC and TPS), well I didn’t get to the mass air flow sensor. I cleaned the whole throttle and it turned out to be nothing. phase sensor (which I didn’t even think about) so don’t be lazy and get to the service center.

I didn’t have time to tinker with the car today, I think tomorrow!

From the heart! Very useful! Good luck on the roads!

Computer diagnostics in identifying the cause of a poorly starting engine

It is impossible to fully check the Lada Priora in order to identify the reasons why it starts poorly when cold or even when hot without specialized equipment and qualified specialists. Nevertheless, we will tell you several useful positions that you can check yourself.

The easiest way is to check the performance of the car's cylinders. For this purpose, remove the engine protection, start it, leave it idling. When the engine has been running for a while, you need to remove the connectors from the ignition modules one by one.

In this case, you need to be more careful and have fairly good hearing. It is necessary to accurately determine, when switching off, which of the available cylinders changes the operating mode the least. Once you have been able to identify the cylinder, you need to do the following simple work:

• Using a “10” wrench, unscrew the mounting bolts of the modules from the faulty cylinder and any other cylinder.
• Replace and secure the cylinders as required.
• Repeat the work with switching on and auditory detection; if the signs of poor starting of the unit move to another cylinder, then the problem clearly lies in the ignition module.
• If you do not see a change, then change the spark plugs yourself.
• Repeat the procedure again. We found that there are no changes, which means the cylinder is worn out or there is a problem in the injector.

Let’s not forget about the main sensor responsible for starting the LADA Priora engine – the mass air flow sensor. It is the sensor indicated above that reads the fuel into the cylinders, after which, based on the data from this very sensor, the fuel supply is dosed by the control unit. This always happens because the sensor we designated shows that more air is flowing, but in reality the indicators are not critical.

A competent diagnostician and his specialized equipment will help you easily find the cause of the malfunction. However, some experienced owners of LADA Priora can easily identify malfunctions in the sensor on their own; for this purpose, you need to remove the connector during actual work. Depending on the type of control unit, the speed will immediately drop and the car being diagnosed will stall, or it will rise to 1500 rpm.

In addition to everything indicated, a poor start of the power plant can be influenced by the actuator abbreviated as IAC (stands for idle speed control), an auto device such as TPS. In this case, only computer diagnostics will come to the rescue.

When a VAZ 2110 car starts and then stalls: our actions

Quite often during the operation of a car, a problem occurs when the VAZ 2110 starts and stalls almost instantly, and sometimes the engine stops working even at low speeds. This problem, of course, is faced not only by owners of domestic cars, but also of foreign cars. Any model is susceptible to this.

Many drivers do not know how to act in such a situation and begin to panic, feeling helpless. There is no need to senselessly pull on wires and pipes, much less kick the wheel. Such actions will definitely not help in determining the cause of the malfunction and eliminating it.

Another situation arises when the majority of car owners calm down if the car still starts after some time, and considers: the car started - that means everything is in order! But the problem remains, it has not been solved, and a similar situation is repeated. And again panic begins, to which is added indignation due to the fact that the malfunction was not eliminated at the very first occurrence of a similar picture.

The reasons that a car stalls at idle immediately after starting are different, and they most often depend on the model or generation of different brands of cars. This could be a clogged valve in the gas distribution system, or burnt relay contacts in the fuel pump.

Some car enthusiasts are able to carry out simple work to identify the problem and fix it later. For those who do not belong to this category, it is recommended to go to a car service center or call a tow truck if you still cannot start.

This is interesting: Why should the air conditioner in the car work even in winter?

The starter turns, but the Priora does not start. A familiar problem. We know how to solve it.

Lada Priora Sedan 16kl Kvartsukha Logbook REPLACING THE FUEL FILTER

• 1. The fuse has blown. In this case, you will need to check its integrity. To do this, you can use a special indicator in the form of a screwdriver or a tester. If these tools are not at hand, you will have to wait for help from passing drivers;
• 2. The terminals on the battery have oxidized or it is simply discharged. This seemingly typical car malfunction can serve as another reason. If the battery does not have enough voltage, it will be able to turn the starter, but there will not be enough charge to power the engine. It is worth checking the device to rule out this possibility;
• 3. Defective ignition switch;
• 4. Corrosion. It can appear on any electrical part of the Priora. First of all, it is worth checking the starter itself, because it is always open to the flow of moist air, and this is the main cause of oxidation;
• 5. The ignition coil is faulty. This can also be checked by calling. For these purposes you will need a tester. If this part malfunctions, it must be replaced.
• 6. Accumulation of condensate under the hood of the Priora;
• 7. Problems with the fuel supply system. This is very common in this kind of trouble. There are a whole bunch of devices that are responsible for the smooth operation of the system. It is not always possible to fix the problem yourself, so it is better to turn to professionals;
• 8. Candles are flooded. And this problem can arise for every car enthusiast. In this case, it is imperative to use a spark plug tool to remove the spark plugs and then check their functionality. Sometimes just wiping them is enough, but sometimes they may need to be replaced. It is better to carry them in the trunk for this occasion;
• 9. Engine overheating. This is another nuisance that can lead to the car's operation being suspended. There could be many reasons for this. For example, there may simply be a leak of coolant from the expansion tank. There are many tubes coming out of it, so each of them may be faulty. Unstable operation of the thermostat, which is responsible for starting the engine, can also lead to the inability to start it. There is only one piece of advice here - immediate replacement of the unit. There is so-called internal overheating, which is much worse than external overheating. While all sensors will definitely report the second option, the second option is practically indeterminable. You need to immediately contact the service for help.

Methods for diagnosing the idle air regulator (IAC)

The most common cause of the described problem, as well as the fact that the car cannot be started at all, is a malfunction of an engine part such as the idle air control. This happens most often on domestically produced cars. There are several possible situations where an IAC malfunction may occur. While the car is moving, a short-term stop occurs, as a result of which the engine stalls when hot immediately after it starts, or refuses to start at all.

After the engine has started, normal idle speed is restored only when the gas pedal is pressed at least once. Observation of similar behavior is possible with a cold engine. The initial attempt to start the engine is unsuccessful, normal operation is restored only after pressing the gas pedal.

In different situations, it may be enough to either press the pedal once or hold it until the engine warms up. An IAC malfunction may occur during sudden braking, when the engine stalls unexpectedly, and restarting shows a normal idle speed above 1500 and within 2000 rpm.

If this is the case with your car, you can try washing the IAC and throttle assembly using a special solution. If the problems do not go away, the idle air control will have to be replaced. Over time, some components may wear out naturally.

Compression

If the 16-valve Priora has difficulty starting when cold, and all the options described above are not suitable, then it is worth checking the compression. In this case, with low compression, starting a cold engine can be very difficult.

When engine parts are warm enough, they expand. Even a slight expansion will be enough for the compression to rise and the engine to start. If the engine is cold, there is no expansion. Therefore, starting will be difficult.

Problem with the injector: features

Most modern cars have a forced fuel injection system. Therefore, such a situation when a car stalls while driving is quite common and can be caused by the erroneous use of an injection engine. There is no need to disconnect the battery while the engine is still running. You should resort to using a cigarette lighter in the most extreme cases, minimizing its use if possible.

Injector for VAZ 2110

In general, it is better to exercise extreme caution with the power system. Such actions can have a detrimental effect on the sensitive injector. If possible, it is better to leave the mass on. Otherwise, the data on your computer may be lost. It is advisable to let the engine run for about three minutes at idle speed. If charging and starting devices are used with the injector, the electronic control unit may burn out.

If the car in the circuit has a neutralizer, then when trying to start the vehicle it is better to avoid towing or driving downhill. This results in the formation of fuel that has not been used, and this can lead to spontaneous combustion if it enters the converter. Avoid getting water into the engine. To do this, you should promptly replace fuel filters and fill in high-quality gasoline.

The engine stops while running - reasons

1. Poor quality fuel is the first thing that comes to mind for most of us, and besides, this is where we need to start looking for the reason for the engine stopping while driving. You will be “lucky” if this happens immediately after refueling, in which case you can confidently say that the problem is in the fuel. Treated by draining the fuel and replacing the fuel filter.

2. Candles. As a rule, suspicion most often falls on them, after bad fuel, of course. Everything is simple here - unscrew the spark plugs and check their condition, replace the spark plugs if necessary.

3. Fuel filter. A seriously clogged filter can cause an interruption in fuel supply, causing you to rev the gas and the engine to stall while driving. To eliminate the problem, simply replace the fuel filter.
