We will need:

The Soviet hammer - they haven’t come up with a better one yet!

Screwdriver crosswise

Set of drifts

Replacing the fuel pump in detail with a description of each step

The algorithm of actions is as follows:

Remove the negative terminal from the battery. A mandatory requirement if you carry out any work that affects the electrical system of your car.
The fuel pump is located under the rear seat. The rear seats need to be raised, I remove them altogether. It comes off easily. You need to “pull the string” in the center of the seat and remove it.
Pull the loop and pull it up
We lift the rug and clean out the dirt in the seat. It must be clean, as this dirt can get into the fuel tank.
The contour of the slot is indicated in the figure
Raise the slot
Disconnect the fuel pump connector to relieve pressure in the fuel system.
Next, under the hood, unscrew the cap from the fuel rail, and use a screwdriver to press the breather (nipple) - this releases the pressure.
Relieving pressure from the fuel rail using a screwdriver
Put the cap back on. Below I will describe an alternative option for relieving pressure in the fuel frame.
Unscrew the 4 bolts securing the fuel pump.

Next, using a hammer and a drift (chisel or straight screwdriver), we “scroll” the pump counterclockwise.
Next, remove the lock washer by simply pulling it up.
And take out the fuel pump.

An alternative option for relieving pressure in the fuel rail

The main method is a little inconvenient and dangerous. Since gasoline can ignite, and if the muffler pants have not yet cooled down, it can cause a fire in the engine compartment. Therefore, there is an easier way.

Disconnect the power supply from the fuel pump.
Start the car and let it run until it stalls on its own.

This method also relieves pressure in the fuel rail. Its advantage is that if you have a 16-valve engine, you do not have to remove the cover from it to get to the nipple!

Choosing a fuel pump for the Lada Granta

The fuel pump is universal and fits all models of the VAZ family.

There isn't much choice. There are two models on the market, and according to reviews, they do not cause problems. You can take any one.

The fuel pump on Kalina, Priora and Grant is the same!

Replacing the fuel pump on a Lada Granta

The fuel pump of the Lada Granta car is equipped with electric submersible fuel pumps. The pump supplies and circulates the mixture in the fuel system. Recently, the car has been equipped with an electric submersible fuel pump from the Bosch brand. This device has the following characteristics:

rated voltage - 13.5V, operating - in the range from 6 to 15 volts;
maximum volume of pumped mixture
the frequency of replacing the fuel filter is 1000 operating hours;
range of fuel classes: AI-92 - AI-95.

Signs of a fuel pump malfunction

Fuel pump breakdowns are reflected in the following “symptomatic series”:

pressure drop in the fuel system;
noticeable decrease in car power;
inability to spin the engine to the cutoff;
extraneous sounds (grinding) when the car is running.

The presence of these fault markers requires a complete replacement of the part or maintenance of the element - clean the Lada Granta fuel pump and replace the mesh.

Replacing the fuel pump on Grant

Before changing the fuel pump on a Lada Granta, the motorist must relieve the pressure inside the fuel lines. To “zero” the car’s fuel system, you must:

Put the Granta at neutral speed;
Apply the parking brake;
Remove the rear sofa;
Disconnect the wiring from the fuel pump;
Start the Lada and wait for it to stall;
Crank the starter for a few seconds.

To work with the fuel filter, the car enthusiast will need:

flathead and Phillips screwdrivers;
spanner set to “10”;
hammer;
rags.

After resetting the fuel lines, it is necessary to remove the terminals from the battery so that the possibility of supplying power to the fuel pump is completely excluded.

Installing a new fuel pump

The first step is to open the fuse panel (on the left side of the front panel) and remove the element responsible for the operation of the unit.

Next, dismantle the rear sofa and remove the plastic trim. Below it is the fuel tank flap (on the right side). The hatch cover is held on by four screws - remove them using a screwdriver. Next, disconnect all the fittings from the cover of the old fuel pump.

Using a “10” wrench, unscrew the nuts of the pressure ring of the fuel pump, of which there should be 8 pieces along the entire diameter of the ring. Next to the clamping ring there is a pin with which the ground wire is in contact. We throw off the wire, and then completely remove the clamping ring. The ring unscrews counterclockwise; for ease of dismantling, it needs to be tapped with a hammer.

You need to make sure once again that all wires and lines adjacent to the part are disconnected. Only then can you remove the used unit and place a new one in its place. You also need to install a new O-ring between the tank opening and the pressure ring - it is made of rubber and wears out quite quickly.

Installation of a new pump is carried out in the reverse order. Before disassembling, draw a diagram or photograph the original location of all fittings and hoses on the fuel pump cover.

Cleaning the part

Replacing the Lada Granta fuel pump in some cases is not the only way to get rid of fuel supply problems in some cases. To restore the functionality of the fuel pump, it requires thorough cleaning. To do this, you need to dismantle the unit using the method described above.

Next, unscrew the lower part of the fuel pump cup. The glass has a filter mesh that needs to be removed using a screwdriver. The mesh will need to be cleaned with a rag and rinsed in solvent. After this, the remaining elements of the fuel pump are cleaned.

After cleaning is completed, it is recommended to install a new coarse mesh, as the cells on the old one may be damaged.

Before performing work, read the operating instructions so that you know in advance where the Lada Granta fuel pump is located, as well as how to attach it. It is better to carry out work in a well-lit room away from open flame sources. For protection, use gloves to avoid damaging your skin with gasoline or solvent.

Procedure for replacing the fuel pump mesh on a Lada Granta

Since the fuel filter on a Lada Granta car is located directly in the tank, it must be removed from there. To do this, one half of the rear seat is folded back, after which the two screws securing the hatch are unscrewed. Below it is the fuel pump. To remove it, you need to do the following:

Relieve pressure in the vehicle's power system
Disconnect the block with power wires
Disconnect the two fuel pipes from the fuel pump cover.
Move to the side the retaining ring that secures the pump in the tank
Pull out the entire module assembly

After this, you can begin removing the mesh filter without any problems.

We move a little to the side three latches - latches, which are clearly shown in the photo below.

Now we move the lower container to separate the module into two parts, first disconnect the tube, which is shown in the photo.

Now we completely separate the two parts of the module.

Now we have full access to the mesh, and it is enough to pry it with a screwdriver so that it moves away from its seat. You may have to apply a little more force than expected, but you can remove it without any problems.

As a result, we obtain a removed strainer, which, as can be seen, is quite heavily contaminated, although in this example we are considering a car with only 65,000 km mileage.

Now we take a new mesh and install it in its place in the reverse order.

In the photo above you can see the black rubber plug. Of course, it must be removed before installation. Also thoroughly rinse the pump container inside and out so that there are no particles of dirt or other debris left on it!

To do this, it is best to use a special carburetor or injector cleaner, such as the one shown above. Then you can assemble the entire structure and install it in the gas tank.

Before starting the Granta engine for the first time, it is necessary to pump fuel several times without starting the engine: pumping two or three times is usually enough. Now you can start the engine and check the result of the work done. The mesh should be replaced regularly, as this example shows that even with a short mileage it is already quite dirty.

The price of a new fuel pump mesh for Grant is about 50-70 rubles.

Removing the fuel pump Lada Granta

If the engine power of a Lada Granta car drops, increased noise occurs, or whines are periodically heard when the fuel pump is operating, then most likely the fuel pump has failed. First, check the pressure in the fuel supply system by connecting a pressure gauge to the fitting on the fuel rail in the engine compartment. If the pressure in the power system is higher than 400 kPa (4.0 kgf/cmg), then the pressure regulator installed in the fuel pump module is faulty and must be replaced (see “Repair of the Lada Granta fuel module.”)

If the pressure in the power system is below 380 kPa (3.8 kgf/cmg), replace the fuel filter (If this does not help, try removing the module and washing its receiver screen.

If in this case the pressure does not increase, the fuel pump must be replaced.

Tools needed to replace the Lada Granta fuel pump

You will need: Phillips screwdriver, drift, hammer.

Operations performed when removing the Lada Granta fuel pump

Removing the fuel module is shown on a car with a VAZ-21116 engine. On cars with other engines, this work is performed in the same way.

1. Reduce the pressure in the supply system. 2. Fold the rear seat cushion forward. 3. Lift the cut out parts of the carpet and the thermal and noise insulating lining above the hatch at the base of the body.

4. Remove the four screws securing the hatch cover above the fuel module...

5. ...and remove the cover.

6. Disconnect the wiring harness block from the fuel module by releasing its spring clip.

7. Disconnect the fuel hoses from the module fittings by pressing the buttons of their spring clamps and sliding the hoses along the fittings.

Disconnect the hoses from the fuel module fittings carefully, avoiding lateral forces, so as not to break the fittings. 8. Using a screwdriver, slide the spring plate of the fuel module bayonet mount counterclockwise and turn the plate until the seven cutouts in it align with the protrusions on the fuel tank flange.

9. Remove the plate.

At the factory, the spring plate securing the fuel module is tightened (or, if necessary, unscrewed) with a special tool. If it is absent, a strongly tightened plate can be moved out of place with light blows of a hammer, resting the drift on the bent upward tendril of the plate. 10. Remove the module from the tank by tilting it to the side...

11. ...to avoid bending the fuel level indicator sensor lever and turning the float on the lever. Otherwise, the indicator readings in the instrument cluster will be incorrect.

When removing the fuel module from the tank, immediately place a cleaning cloth under it, as gasoline may leak from the module’s glass.

12. Remove the rubber O-ring from the tank flange. Be sure to replace a heavily compressed, hardened or torn ring to avoid gasoline leakage.

13. Install the fuel module and all removed parts in the reverse order of removal. After installation, slightly tighten the spring plate of the module fastening with light blows of a hammer through a drift (see note above). When installing the module into the fuel tank, the installation arrow on the module cover must be directed towards the rear of the vehicle.

When connecting fuel lines, follow the direction of gasoline supply indicated on the fuel module fittings

Replacing the fuel pump (gasoline pump)

The main reason for the failure of the fuel pump on the Lada Grant is symptoms such as a drop in pressure in the fuel system, a strange sound from under the rear seat, similar to a periodic howl, or unstable engine operation. If you find out that the cause of all these symptoms is the fuel pump, then you should replace it. Since the Lada Granta and Kalina cars are almost identical in most of the parts used, the procedure for removing and installing the fuel pump will be identical.

Guide to replacing the fuel pump on a Lada Granta

So, the first step is to reduce the pressure in the fuel system by removing the pump fuse.

After this, you need to raise the rear seats and lift the floor trim in the place where the cut is located, closer to the right side of the car.

There you will see a black cover like this, under which is the part that interests us. To unscrew the cover you will need a Phillips screwdriver.

After this procedure, remove the pump cover by lifting it up:

Next, you will see the following picture, as shown in the photo below:

As you can see, now you need to disconnect the power plug from the fuel pump, which is located on the left, and the two fuel fittings, located on the right. They are secured using plastic and metal fasteners. To remove the lower fitting, you need to press on the metal bracket and pull the tip towards removal; it is most convenient to do this with pliers:

Then, when everything is disconnected, you can begin to knock down the retaining metal ring that secures the Granta fuel pump. This procedure can be carried out using a screwdriver and a hammer by placing the screwdriver on the protrusion in the ring and tapping counterclockwise several times until the ring comes free.

Now you can remove the ring and then the pump itself. Please note that before this work you need to thoroughly wipe everything around so that there is no dust or other foreign objects. Otherwise, all this may penetrate the tank and, accordingly, ultimately clog the mesh of the new fuel pump. We take out the part, carefully, and take it out a little to the side at an angle so as not to bend the fuel level sensor float.

That's basically the whole replacement. After everything has been done, you can begin installing the new mechanism and carry it out in chronological order!
