The gasoline pump is an integral part of the power system of a gasoline engine. In order for the pump in the Lada Kalina model to function uninterruptedly, there must be a working fuel pump relay in its electrical supply circuit.
The pump takes in a portion of fuel, which is traditionally located in the tank. In Lada Kalina, this container with gasoline is located in the rear of the body. There are special pipelines as lines that transport fuel not only to the ramp with injectors, but also back to the tank. Using a pump, a certain amount of pressure is generated in the fuel rail, which allows the injectors to spray gasoline in the form of a torch (the so-called “fog”). The fuel pump fuse also plays an important role.
About the reasons for the failure of the fuel supply system
As noted, in the Lada Kalina model the fuel pump is equipped with an electric drive. This provides a number of specific and important benefits. Here the priority is simplicity in design and reliability, allowing the device to have an impressive service life. We also note the high safety when the fuel supply system stops functioning when the engine is stopped. In order for the pump to “live for a long time”, it requires high-quality gasoline, which also serves as a coolant for the device.
So, more about the main reasons:
- Fuel with quality standards that do not meet standards. This leads to gradual clogging of the filter and incorrect operation of the gasoline supply unit.
- Open circuit in the electrical power supply circuit of the pump. Here the culprit may be not only the fuel pump fuse, which, by the way, should be checked as a priority, but also the fuel pump relay. Also among the reasons may be oxidized contacts of the pump power supply or broken supply wires, which happens much less frequently.
In any case, if the pump does not work, then a thorough diagnosis of the entire fuel supply circuit will be required; you must check the pump fuse, as well as the fuel pump relay.
First block: location, what it consists of
The first system is located under the cover, next to the speed switch, slightly below the ashtray. Knowing where the Kalina fuel pump fuse is located, you can troubleshoot many problems. To pry off the cover, just use a flat-head screwdriver.
The numbers in the image correspond to the numbering: 1. Power circuit; 2. Fuel pump; 3. A circuit designed to continuously power the ECU; 4. Connector necessary for diagnosing the condition of the ECM. If the Kalina fuel pump fuse stops working, you need to carefully remove it using tweezers or another device, then insert another one. When performing these manipulations, the battery must be disconnected.
Changing the fuel pump relay
In Lada Kalina, this electrical element is located in the cabin, more precisely below the panel and close to the air duct grille. To provide access to the specified relay, you will need to remove the cover of the mounting block. In this case, you will need a small flat-tip screwdriver.
Before directly removing the fuel pump relay, don’t be lazy to check the fuse, which is also located in the block, but near the transmission lever and ashtray. The fuse link jumper must have a complete appearance. If there is a malfunction, then replace the fuse with a new insert with a similar current rating. To remove the element from the mounting socket, use tweezers.
Having made sure that the fuse is intact, but the pump still does not work, we move on to checking the relay. There is a certain nuance here. A faulty relay is dismantled using a socket-type wrench, so we stock it up in advance.
When all the faults present in the pump’s power circuit have been eliminated, we start the motor and verify the functionality of the device. If the fuel pump still does not work, then more in-depth diagnostics of all components of the power system will be required.

Troubleshooting pumps
Now let's move on to consider the situation when the reason lies directly in the fuel pump itself. Replacing a unit is a drastic measure that can be avoided in almost the vast majority of cases.
Scheme
- To check the LADA Kalina pump, you will need to dismantle it.
- Access to the device location is provided through the rear of the cabin. To do this, you will need to remove the rear seat cushion.
- The pump module is closed with a special cover; when removing it, you will need to remove the fixing fasteners.
- When the ignition is turned on, the pump may not pump at all or supply fuel intermittently. If this is present, the device requires maintenance or replacement.
- The further dismantling process involves removing the cover and disconnecting the pipes.
- Now you can unscrew the locking ring, after which you need to carefully remove the pump from the cavity of the fuel tank.
- We carefully inspect the dismantled unit for clogging of the filter present in its module, which is made in the form of a mesh. If it is not very clogged, then it can be washed, but when there are breaks and a high degree of contamination, then no alternative replacement is required.
This type of routine maintenance is not covered by the Lada Kalina operational manual. Despite this, the mesh on the pump should be replaced every 50 thousand km of the distance traveled. Such experience has the right to life due to the insufficient quality of domestic fuel.
Determining the need to replace the pump filter component is not difficult. As noted, this is done through visual inspection. Usually the mesh contains a dirty-brown mixture, which includes metal particles and other debris. The bottom of the pump assembly cup is often littered with solid particles of various natures.

Regarding the previously mentioned possibility of washing the mesh, many experts have a negative attitude towards this practice. Compared to the labor costs of dismantling the pump, the cost of the mesh itself is quite insignificant - about 100 rubles. It would be more rational and correct, in our opinion, to replace it, the main thing is to know where it is.
Second system: where is it located?
The remaining Kalina fuel pump relays are located on the right side of the dashboard, not far from the air duct, also under a special cover.
First you need to remove the corner screw, then open the cover completely and remove it.
To remove the Kalina fan relay, you need to use a ten-socket socket wrench.
Then you need to carefully remove the wires, remove the unit and the Kalina cooling fan fuse. This is difficult to do, since you need to avoid damaging the wires. Upon completion of removal, the block will look as shown in the picture.
The presented unit includes the following elements: 1. Turning on the cooling fan (low speed); 2. Main relay; 3. Turn on the cooling fan (high speed); 4. Engine cooling system fuse; 5. Fuel pump relay. Now you know where the fuse for the fuel pump on Kalina is located.
About work culture and regulations
The fuel system of LADA Kalina (and not only) requires cleanliness of both the gasoline itself and the components involved in its supply to the engine. All dismantled parts of the system must be perfectly cleaned and washed before reinstallation. When replacing the mesh, we also recommend replacing the filter used for fine fuel purification. Where is this filter located? It is located inside the right stern wheel arch near the jack stand cup. According to the regulations, this element requires replacement no less than after 30 thousand kilometers.
Note that there are two more mesh filters along the fuel path in the circuit, one of which is installed in front of the fuel pressure regulator, and the second directly in front of the injectors. These filters “take over” fuel that has already been practically purified in the preliminary stages, so the need to replace them is extremely rare.
Troubleshooting the Kalina fuel pump
If the electrics are working correctly, the fuel pump remains the object of close study. Replacing the fuel pump assembly is an extreme, and not at all mandatory, measure.
Electrical diagram for connecting a fuel pump
If the fuel pump does not turn on during normal electrical operation, remove the device to check the fuel pump. To check the functionality of the fuel pump, you need to remove the cover, which is located in the rear of the car, and remove the unit itself.
If the pump does not pump or pumps intermittently, it may be necessary to replace the Kalina fuel pump mesh. We remove the cover, disconnect the hoses and wires, use screwdrivers to press out the retaining ring and gain access to the pump. The device itself is located in the gas tank and takes gasoline directly from the tank.
Routine work, which would include replacing the mesh, is not specified in the operating instructions for the Lada Kalina. Repairing the fuel pump in order to replace the mesh should usually be carried out after 50 thousand kilometers, since the fuel at Russian gas stations is generally of low quality.
During dismantling, this can be assessed visually; the mesh turns from white to dirty brown interspersed with mechanical residues of metal, dirt and oil. At the bottom of the glass, when dismantled, you can see solid particles of unknown origin, which could only get into the tank when refueling.
There is also the opinion of some experts about the possibility of washing the mesh without replacing it. But taking into account the cost of this part, which does not exceed 100 rubles, the feasibility of flushing during the rather complex procedure of removing and installing the fuel pump is highly questionable.
Separately, it is worth pointing out the culture of repair work: after disassembly, all parts must be cleaned of dirt and foreign impurities, thoroughly washed and installed in their original place without the use of excessive force. When replacing the mesh, it is advisable to replace the fine filter, which is located in the rear right wheel arch near the jack cup. Routine work to replace the filter is provided for during maintenance every 30 thousand km.
When pumping gasoline to the nozzle, 2 more grids are installed along the way to clean the fuel. One is located in front of the fuel pressure regulator, and the last cleaning line is installed before the injector inlet. But before these filters, gasoline arrives in a dirt-free state and fault diagnosis based on these barriers is practically not carried out, due to the low probability of the need for replacement.
The fuel system of the Lada Kalina car is a reliable and well-functioning combination of units that can ensure uninterrupted operation of the car for a long period of time with timely and correct maintenance. They include a mandatory replacement of the fine filter every 30 thousand km and, highly desirable, replacement of the fuel pump mesh after approximately 50 thousand km.

Let's sum it up
The fuel system in LADA Kalina is a capricious mechanism that places increased demands on the quality of gasoline and the timeliness of routine maintenance. The uninterrupted functioning of all components in the system is possible only if these two main conditions are met. Let us remind you that owners should replace fine filters no later than after a mileage interval of 30 thousand km, and you now know the pump grid after every 50 thousandth mark, where each component is located.
The fuses and relays for the fuel pump and engine cooling fan are not located in the main unit, but in the additional unit. Moreover, there are even two of them. One of them is located under the cover near the gearshift lever, just below the ashtray. You can open it by simply prying it with a flat screwdriver:
Let's take a closer look at what it all looks like and which element is responsible for the operation of which device:
The numbers in the picture correspond to the numbering below:
- Main relay power circuit
- Fuel pump
- ECU constant power supply circuit
- ECM diagnostic connector
If one of the fuses fails, remove it with tweezers and insert a new one. The battery must be disconnected while this work is being carried out.
The second additional fuse and relay box is located on the right side of the instrument panel at the very bottom near the heater air duct, under the cover. Look clearly at the photo below:
First, unscrew the screw, which is located in the very industrial corner, and then remove this cover completely.
Now, to remove this relay block, we need a 10mm open-end or socket wrench.
After this, we move the wires to the side and carefully remove the entire block with the relay and fuse. Removing it is quite inconvenient, since rather voluminous wiring harnesses will get in the way. This is what it looks like after removal:
Now let's look at this mounting block in more detail:
- Turning on the engine cooling fan (low speed)
- Main relay
- turning on the engine cooling fan (high speed)
- fan fuse
- fuel pump relay
If one of the above elements fails, remove the burnt one and put a new one in its place. We put everything back in the reverse order.

Before replacing the fuse, the cause of the blown fuse must be determined and eliminated. To avoid failure of elements of the engine control system, do not install fuses with an increased rating or homemade ones. Sometimes the fuse thread remains intact, while its connection inside the fuse is broken. It is impossible to visually determine such a malfunction. In this case, you can assess the condition of the fuse using an ohmmeter. You will find a full description of viburnum fuses below.
