Quite often, VAZ 2110 owners are faced with a problem: the VAZ 2110 starter does not turn the injector 8 and 16 valves! In today's article we will look in detail at the main causes of this problem and consider ways to eliminate it.
The starter on the VAZ 2110 is a simple brushed DC motor, powered by the car’s battery. It should be noted that at any engine speed its power will be quite high; this parameter of collector internal combustion engines is well implemented in the unit. Even if the load on the device varies, the power level will always be the same. However, if the device works slowly or poorly, turns, clicks, but the internal combustion engine does not start when you turn the key, then you need to pay attention to diagnosing each component.
The starter on the VAZ-2110 does not start, does not turn or click: what to do?
The main task of the starter in a VAZ-2110 car is to start the rotation of the crankshaft so that the operation of the fuel system begins.
When the driver turns the ignition key and the car does not start, he has to look for the reason why the starter does not work. Although the operation of this unit is necessary only in the first seconds of starting the car, it cannot be done without it. Initial diagnostics can be performed without the use of instruments by assessing the performance of the starter on the battery. But it is possible to fully analyze the operation of the VAZ-2110 starter only if you have special measuring instruments. Once a breakdown is detected, you can think about further repair actions.
Diagnostics
The main load during starter operation falls on the relay. When a VAZ-2110 cannot start, they say that the starter does not turn or click, meaning the functionality of the solenoid relay, which in normal condition should make clicks. Such problems often appear in the following situations:
- The rotor “mass” is in contact with the positive charge of the stator.
- The roller or bushing on the electric motor has jammed and stopped rotating.
- A short circuit has occurred between the stator and rotor windings.
Without removing the housing from the starter, these causes cannot be found and eliminated. The click that every driver often hears is created by the mobility of the core between the windings.
The first of them retracts the core for fixation, and the second must hold it in a certain position. When the voltage on the holding winding is insufficient, the core returns to its original position. Every click heard by the driver is an unsuccessful attempt to fix the core. In this situation, the retractor relay clicks, but the starter does not turn, and the car remains in place.
In addition to the traction relay, the cause may be hidden in burnt contacts; it is easy to detect by the unpleasant smell in the car interior. This also sometimes occurs due to a discharged battery. For each case, the solution to the problem is selected individually.
No contact
The starter starts with difficulty, before clicking. At first you are only slightly alarmed, but the situation repeats itself again and again: first it clicks, and only then the engine turns.
Have you checked your contacts lately? You need to start with the battery, maybe you are wrong to blame the starter, and the reason is oxidation of the terminals. Have you cleaned them and the starter clicks again? You need to check how your VAZ has ground contact with the body, and then the contacts of the starter itself, because they are also prone to oxidation.
Another test method: ask someone to turn the ignition key, while you yourself knock on the relay, using only a hard object. If it starts, it means that the closing contacts (nickels) are stuck, and it is easier to change the relay than to disassemble and repair it.
The starter clicks but does not turn on a VAZ 2110: what to do?
If your starter is faulty, then it is impossible to start the car, so urgent repair of this unit or its replacement is necessary. In this case, it is often quite problematic to deliver it to the nearest service station, so it is best to learn how to do the repairs yourself. Owners of the VAZ-2110 should learn how to restore performance on their own, this will reduce the cost of car maintenance.
Why doesn't the starter turn over?
Depending on what caused the starter to fail, it is necessary to take the next steps - repair or replace the unit. In addition, in some cases, you do not need to repair the starting device itself, but manipulate other components. In most cases, you can get by with repairs, but experienced car enthusiasts recommend immediately replacing the unit so that there are no more problems with it.
- Most VAZ-2110s do not have a standard injector, but many car enthusiasts install this unit themselves. It helps reduce fuel consumption, helps start the engine in cold weather without warming up and increases power. The injector fails, and along with it the starter, due to low-quality fuel. Another reason may be failure to follow the connection diagram, but then you will discover a malfunction immediately after installing the injector. Otherwise, you need to flush the injector to remove any suspended matter that is carried into it by the fuel.
- If the car starts, but after a short stop the engine cannot be restarted, then the problem lies in the overrunning clutch. At the moment of failure, you may hear clicking sounds from under the hood and notice that the car radio begins to turn on by itself. In this case, you need to cool the power unit before restarting or not make short stops. You will also need to replace the overrunning clutch with its geared counterpart. Be sure to check the conductors that come from this node. Sometimes, to restore the functionality of the coupling, it is enough to replace the wires that visually look damaged.
- The retractor part of the starter especially often fails. When such a breakdown occurs, the dashboard lights first light up and then go out. Before replacing the solenoid relay, you must close the starter and turn off the alarm. If the listed components are in working order, then you will simply have to replace the relay.
- Clicking sounds in the starter and failure to start the engine are often caused by damaged contacts. In this case, first inspect the battery, clean the terminals if oxide appears on them. Sometimes on a VAZ-2110 it is enough to tap the starter relay to get rid of the problem. Be sure to take an assistant with you who will start the engine while you tap the relay. If with such a rough approach it was possible to start the engine, then it is worth replacing the relay completely. Repair will be impractical.
Repair work
On a carburetor VAZ 2110 it is easier to replace the fuel pump if necessary. It is located under the hood and is not difficult to get to. It is enough to disconnect the pipelines, then unscrew the pump itself.
The electric fuel pump installed on an injection machine is located directly in the gas tank, so it is more difficult to get to it; this is done from the passenger compartment by removing the rear seat.
All fuel pumps are dismountable. After removing the cover, the mesh is removed and its condition is assessed. Of course, you can wash it, but it’s even better to replace it right away. Before starting repairs, you should purchase a repair kit, which must be equipped with a mesh.
VAZ 2110 starter does not turn, clicks: causes of malfunction
All cars use a starter to spin the crankshaft when starting the engine. The power of this device allows the crankshaft to overcome compression in the cylinders and frictional forces. If the starter does not turn, then the engine cannot start, as a result, the car stands still. For a motorist, the worst situation occurs when, when turning the key, he hears clicking sounds in the power plant or silence.
By the “silence” of the engine it is impossible to determine what exactly is not working. It’s good if it’s a starter, since repairing or replacing it won’t be as expensive as repairing a VAZ 2110 engine. There can be many problems with this element; this article contains the main faults and ways to solve them. If you want to repair or replace it yourself, then this will require a connection diagram, since the starter is an electrical device.
The injector can also fail
In fact, we have sorted out almost all starter malfunctions associated with the operation of the VAZ 2110 carburetor engine. There are also injection engines, which are fashionable to install on cars today. Yes, they are more environmentally friendly, reduce fuel consumption, increase power performance, and the engine does not require warming up in winter.
But the injector is unlikely to “rejoice” at insufficiently high-quality gasoline; its repair is more expensive, since it operates under the control of a microprocessor. And in our operating conditions, this can also be the reason why the starter does not work well. Perhaps the injector requires cleaning (and this should be done regularly, since low-quality gasoline contributes to the deposition of resins and impurities).
Safety block, wires, terminal blocks
The so-called black box of the motorist, in which fuses and relays are located, quite rightly comes into question in such situations. A short circuit or simply stagnation of contacts may occur in the block. Experienced motorists recommend not hitting the block too hard, this really helps.
If that doesn’t help, find the terminal blocks with the power wires and clean them thoroughly from oxides. Then carefully solder everything.
You can also test the ignition switch and clean the chips whose wires go to the starter. It is better to replace the nuts on the terminals with brass ones to make contact better.
Starter and retractor
It was said above that the first thing to check is the solenoid relay. However, it is no less important to test the starter itself, especially if the above checks did not yield anything. The best remedy is to install a known working starter and check how everything works.
Thus, it becomes clear why the starter starts every other time. The reason for this is either the contacts, the fuses, or the starter itself.

The wiring diagram for hatchbacks 2112 is a unique thing in itself. In order for voltage to appear on the solenoid relay, the following parts must be in good working order: the ignition switch, the ECU unit and two more relays - the main and additional ones. Some cars do not have an additional relay, which can be considered good luck. But, if when you turn the key on a VAZ-2112 the starter does not turn, then the fault must be looked for in the wiring. A broken immobilizer code can also cause problems. The last malfunction can be cured by replacing the ECU or disabling the immobilizer. Well, let's look at something simpler.
Example in the video: the immobilizer was damaged and the starter stopped working.
Answers to frequently asked questions
How can you tell if the starter relay is not working?
To determine whether the starter relay is working, apply power from the positive terminal of the battery directly to the control contact of the relay. After this, a click should sound; if it is faulty, there will be no sounds.
How to check whether the starter is working or not?
To check the serviceability of the starter itself, you need to apply current to it directly by connecting the power wires of the retractor relay (thick wire from the battery) and the electric motor (stud with a thick wire from the retractor to the starter). A working starter should start moving.
What to do if the starter does not work after turning the ignition key?
First, make sure there is voltage at the battery terminals. If you don’t have a tester, this can be done using a 12 V lamp. Then try to apply voltage directly to the starter: use a screwdriver to close the pin to which the wire from the battery goes and the control contact located nearby. If there is no reaction, check the quality of the contacts of the terminals on the battery, the ground contacts (with the body and the engine) and the contacts of the starter itself by cleaning and tightening the terminals. If the battery is discharged or the starter is faulty, you need to start the car with a pusher (manual transmission) or tow it to the repair site.
Why does the starter not work with the ignition key?
The main reasons why the car does not respond to the ignition key:
- control relay failure;
- breakdown of the ignition switch/contact group;
- wire break or short circuit;
- problems with the anti-theft system (alarm, immobilizer);
- breakage of the solenoid relay;
- starter motor failure.
If the starter turns directly, but not from the key, then the last two problems can be eliminated.

All features of the standard scheme
The reader will be surprised, but there will be more than one scheme here. The most difficult option is shown below.
Scheme with additional starter relay
Please note: relay K2 is not “unloading” at all. A significant current flows through the lock contacts, and relay K2 can be called “blocking”: when it does not work, the starter does not turn. Why is this necessary, think for yourself.
If an attacker closes the contacts in the lock, he will not only be unable to start the engine, but also not use the starter. That is, the hijacker will not drain our battery.
The circuit shown above is used with 1.6 liter injection engines. There may be another option - a simpler one.
Scheme without additional relay
There is no blocking relay here. The current flows to the solenoid relay from pin 50. A simple version of the circuit is typical for cars from early years of production. Which applies to the entire “Ten” family, including hatchbacks. That is, an interesting combination occurs: the model is VAZ-2112, and the starter will turn even in the absence of all relays and ECUs!
The starter doesn't turn, what happens?
We know that there are two variants of the scheme. If “option 2” is implemented, voltage to the starter is supplied directly from the lock. But the ignition switch in the “Tens” is short-lived, since 30-40 Amperes are transmitted through it (the current of the solenoid relay). This is true for both the sedan and the 2112 hatchback, and the starter may not turn only because the lock is broken. Draw your conclusions!
All of the above also applies to “diagram 1” - look at it carefully.
The main relay is located in the extension block. It is located under the stove on the right. An additional relay is located in the main unit (see photo). However, it may be missing.
If “option 2” is implemented, check only the lock. And if there is an additional relay, it is not recommended to install a jumper instead. Marked in the photo:
- Additional relay (white arrow);
- Main relay (element “6”).
Is the problem caused by the alarm?
A blocking relay can be installed in the starter circuit when installing an alarm system. And many alarms need to meet certain conditions in order to remove the blocking. The simplest thing: the on-board voltage must be greater than 11 Volts.
Alarm with blocking relay
Conclusion: the starter may not operate when cold if the battery is discharged and the car has an alarm system. So, we remove the battery, charge it and install it back.
When the immobilizer is a hindrance
The engine stalled unexpectedly, the starter refuses to turn it, and it also won’t start with a “push.” The battery was checked - charged, serviceable, terminals clean and in place.
However, your immobilizer is working, and most likely the problem is there. The protection is triggered, the engine is silent. It is necessary to tow the VAZ 2110 to a car service center for diagnostics.
In order to bypass and disable the immobilizer yourself, it is recommended that you read the following article: https://vazweb.ru/desyatka/elektrooborudovanie/kak-otklyuchit-immobilayzer.html
Final check before replacing the starter
We turn the key to position II, and nothing happens... In this case, open the hood and remove the air filter by unscrewing the screw on the body and loosening the clamp on the pipe. The starter is located under the filter housing. In the photo we see the following: someone disconnected the solenoid relay cord.
What we found under the filter
Using a needle probe, we check that when you turn the key, “+12” appears. Then, after checking, we wrap the cord with electrical tape.
Sometimes voltage seems to be supplied to the starter, but the solenoid relay is activated “every time”. Well, try cleaning the terminal - both in the connector and on the starter itself.
- The copper is polished to a shine;
- The wire (see photo) is supplied with “plus”;
- The starter doesn't even click.
The first thing you need to check is the battery contacts. We remove the terminals (key “10”) and look at what is under them. There is no point in measuring the voltage with a probe - it will show “12 Volts”.
Solenoid relay current – 40 Amperes. The presence of a resistance of 0.1 Ohm results in a voltage drop of 4 Volts. So consider... And the starter motor consumes 200 Amperes during operation.
What to buy?
- 2110-3708010, -03, 04 – 9 teeth, 2 holes;
On the right is the BOSCH starter, on the left is PROMO-ISKRA
The choice depends on the type of gearbox. And nothing else.
Chemistry
There is no need to clean copper with WD-40 - after that everything will only get worse. Special equipment needed:
- Ammonia;
- ASIDOL (Lenbytkhim LLC) - excellent, by the way, also polishes glass;
- Molykote S-1002;
- Kontakt 60 or 100 (acid) and WL (wash);
- CRAMOLIN ContaClean (acid).
CRAMOLIN requires a remover. It's easier to take an eraser and ammonia.
