How to remove and replace the fuel pump on a Niva Chevrolet photo and video

How often should I replace it?

It is recommended to change the fine filter every 45 thousand km (in some sources - 30,000 km) or once every 3 years. Replacing the fuel pump mesh is not regulated, so it is done in case of clogging or for preventive purposes every 100 thousand km.

Clogged filter elements lead to a decrease in filter capacity, which can cause you to experience the following problems:

“sluggish” engine responses to pressing the accelerator pedal;
difficult starting the engine;
dips when pressing the gas pedal hard at low speeds. In particularly advanced cases, the engine begins to slow down and may even stall.

Power system design

Until 2006, a fine filter was installed in the engine compartment near the engine shield.

But on most Chevrolet Niva the TF is located near the tank under the bottom. In the absence of an inspection hole, from which it is most convenient to carry out work, the rear part must be fixed on stops in a raised state. The coarse fuel filtration mesh is an integral part of the fuel module and is located in the tank.

When purchasing, be careful, as there are 2 types of design: “rectangle with a cut side” and “sector of a circle” (installed on cars until 2006). For TF of this shape, there is a special molding at the bottom of the glass, so installing a rectangular filter element is undesirable.

The check valve in the fuel module prevents gasoline from draining into the tank after the engine is stopped, so a certain gasoline pressure is always maintained in the system. Before starting replacement, the pressure must be relieved. To do this, you need to start the engine, and then remove the fuel pump fuse. After working for some more time at the residual pressure, the engine will stall.

Replacing the fuel pump mesh

Let's look at how to change the coarse filter yourself.

Raise the right rear seat cushion.
Unscrew the two screws securing the service hole plug.
Disconnect the power connector.
Clean the top cover and the contact areas of the thrust plate as thoroughly as possible from dirt and dust.
Disconnect the clamps and remove the fuel hoses.
Unscrew the 8 x 10 bolts and remove the metal plate holding the fuel module housing.
When removing the module, try not only to drain the gasoline from the glass as carefully as possible, but also not to damage the FLS float.
Assess the condition of the rubber gasket. A seal in satisfactory condition can be turned over during installation. If necessary, replace the gasket with a new one so that there is no depressurization of the tank in this place.
To begin disassembling the fuel module, disconnect the power supply chips.
Pull the fuel return pipe out of the groove.
Unclip the 4 plastic latches around the perimeter of the glass, then detach the glass from the top lid.

The fuel pump mesh sits tightly on the mounting fitting. There is another type of fuel module on the Chevrolet Niva. To replace the TF, just unfasten the glass. When installing a new filter element, the fuel pump must be held by hand.

Replacing the fuel pump mesh on Chevrolet cars

The gasoline pump mesh is part of a part such as a gasoline pump. A seemingly unsightly element can cause serious and costly damage. In this article you will find step-by-step instructions on how to replace the fuel pump mesh in a Chevrolet Aveo and Lacetti. There are often situations in which the gasoline pump on Chevrolet cars breaks down. This is very bad news. Moreover, it is expensive. One of the main reasons is a dirty mesh. As a rule, this happened after the car had traveled more than 60 thousand km. At the time of a breakdown, many questions arise: how to remove the fuel pump on a Chevrolet Cruze or Lanos, can you do it yourself, what needs to be done to prevent a breakdown next time and how much will you have to invest? If you have a situation in which a part has broken, then replacing the fuel pump for Niva Chevrolet, Aveo, Cruz, Lacetti and other models of this manufacturer should be carried out by specialists. But you can avoid this waste or prevent it next time if you have already had a breakdown. The way out of the situation is to timely replace the fuel pump grid of Lacetti, Aveo and others.

We replace the Niva Chevrolet fuel filter with a new one.

To set a Chevrolet Niva SUV in motion, it is necessary that high-quality fuel enters the engine. But before it gets into the gas tank of a car, the fuel travels a long way from oil refineries to gas stations, moving in fuel tankers and pipelines along the way. Then it is stored in an underground container, waiting in the wings. On this path there is a high risk of various small debris, water and other particles getting into it. Over time, condensation may also form in the gas tank. If all this gets into a running engine, then there is a high probability of increased wear of parts and mechanisms. Therefore, such a necessary part as the Niva Chevrolet fuel filter is installed so that the quality of the mixture can be adjusted.

Replacing the fuel filter on a Chevrolet Niva is a fairly simple procedure that can be done independently. Let us consider in more detail the purpose of this part and the main prerequisites for its replacement.

Replacing the Chevrolet Niva fuel filter

Using a 10mm socket, unscrew the plastic TF protection.

Disconnect the fuel inlet and outlet hoses (there will be 2 clips on the sides of the snap connections that need to be pressed into the connector when removed). Despite the lack of pressure in the line, some gasoline will flow out of the hoses.

Loosen the nut of the metal clamp tightening the bolt (if the nut is stuck, the bolt will most likely turn while turning, so in addition to a 10mm socket, you will also need a 10mm spanner).

Remove the old fuel pump from the clamp and pour the remaining gasoline in it into a container prepared in advance.

Install a new filter. Remember that the arrow on the filter housing indicates the direction of fuel flow. All that remains is to install the hoses until the connectors click and assemble the remaining elements in the reverse order of removal.

After replacing the fuel filter on your Chevrolet Niva yourself, turn on the ignition several times for 5-8 seconds so that the fuel pump fills the system with fuel before starting the engine for the first time.

Filter location

This element is built into the fuel line between the tank and the injectors. It is necessary to prevent particles of debris, dust, rust, etc. from entering the combustion chamber.

To ensure maximum cleaning, there was no need to frequently replace components in cars with a two-factor system consisting of a coarse and fine filter.

Coarse cleaning - needed to retain particles with a size of 0.1 mm. It is a fine-grained mesh, which is made mainly of brass. The device is located near the gas tank. In the Chevrolet Niva it is built into the fuel pump. This product can be cleaned by washing, so there is no need for frequent replacement.
Fine cleaning – designed to remove dust and impurities up to 0.001 millimeters in size. This is a cylindrical device, inside of which material with small fractions is placed. Installed between the pump and the fuel rail. It usually fails more often, but replacement is quite simple.

Replacing the Chevrolet Niva fuel pump.

If the fault is still in the pump itself, then it needs to be replaced, which takes place in several stages:

Disconnect the battery.
We reduce the pressure in the fuel line. To do this, you need to loosen the special valve on the fuel rail.
We remove the rear seat cushion and open the hatch above the fuel tank, after removing the sound insulation layer.
We remove the hoses. To do this, you need to squeeze out the special clips of the clamps. It is worth remembering that the gasoline vapors inside can form a lot of pressure, so before disconnecting them you need to unscrew the cap of the gas tank filler neck.
The pump is secured using 8 nuts. Once they are unscrewed, you can remove it. You need to slowly lift it up, then turn it slightly on its side so as not to damage the fuel level sensor.

Symptoms of a problem

Having difficulty driving uphill
extraneous noises during engine operation
increased fuel consumption
difficult engine starting
jerky movement

You should also follow the recommendations for replacement. According to technical regulations, the fuel filter on a Chevrolet Niva needs to be changed every 15,000 kilometers.

How to remove and replace the fuel pump on a Niva Chevrolet: photos and videos

There are often breakdowns in cars related to electronics. And sometimes it is very difficult to detect the cause of a malfunction. A common cause of breakdowns on the Chevrolet Niva is breakdowns with the fuel pump. The main problems of failure of the engine fuel supply system are: breakdown of the fuel pump itself, clogged filter, breakage of supply wires, damage to tubes, failure of fuses or breakdown of the fuel pump control relay. The last reason, although not common, always remains a mystery to most drivers. This part performs electronic functions, and electronics in a car are a dark forest for the average driver. “It’s much easier to rebuild an engine than to delve into the brains of a car,” many drivers would say. In order to clarify the picture of the need for a relay in a Chevrolet Niva, let’s take a closer look at what it consists of and what functions it performs.

Reduced pressure in the system

Replacing the fuel filter on a Niva Chevrolet is carried out in a pit or overpass, since it is located under the bottom of the car. First you need to reduce the pressure in the system. It drops 5-8 hours after turning off the ignition. Another way is to start the engine, disconnect the power terminals of the fuel pump and wait until it uses up the reserves in the fuel hose.

Let's take a closer look at the procedure for reducing pressure in the system:

Raise the rear seat cushion. We unscrew the sound insulation layer that is located underneath.
We find the cover that covers the fuel pump. It is attached to two self-tapping screws that need to be unscrewed.
Under the cover there is wiring with blocks. You need to disconnect them and start the engine to relieve the pressure. We wait until the engine stalls and begin the repair.

Removing and replacing the fuel pump on a Niva Chevrolet

The negative terminal is removed from the battery.
It is necessary to reduce the pressure level in the power system. One way to unscrew the valve on the fuel rail.
You need to get to the back seat and fold back the cushion on it on the right side - the fuel pump is located there.
Having discovered the sound insulation, with a special cutout for the fuel tank hatch cover, you need to bend it.
Disconnect this cover by first removing the screws. Location of screws securing the decorative fuel pump cover
After such small operations, you will have direct access to the fuel pump. The decorative hatch is removed and the fuel pump is visible
You need to disconnect the block with the power wires on the pump.
Remove the fuel hoses by releasing the spring clips. At this point, it should be taken into account that gasoline vapors create pressure in the fuel tank, which, after removing the fuel hoses, will displace gasoline. To prevent this from happening, it is recommended to remove the fuel filler cap before removing the fuel pump. Hose clamps nearby
The pump is secured with eight nuts that must be unscrewed. The fuel pump mounting nuts are marked with arrows
After this, you need to remove the pump, lifting it up, then tilt it so that the fuel level sensor comes out of the hatch. Next, the pump is finally removed.

Installing a new or repaired fuel pump is done in the reverse order.

Pump replacement.

We go down into the inspection pit, where the fuel filter on the Niva Chevrolet is replaced:

Using a 10mm wrench, remove the casing fastenings
Disconnect the tip of the fitting, remove the clamps from the 2 ends of the outlet tube
Loosen the clamp with a 10mm wrench
Squeeze the clamps on the tube and move the filter to remove it from the clamp
Drain the amount of fuel remaining in the filter into a container.

On pre-restyling cars, work is carried out in the same way. But the part itself is located under the hood, on the passenger side, so it is easier to change it and there is no need to install the car on an inspection hole.

After this, reassemble in reverse order. If you have all the necessary tools, the whole job will take 20-30 minutes.

How to change the fuel filter on a Chevrolet Niva yourself

The Chevrolet Niva fuel system requires systematic maintenance. If this is not done, the driver will be in for unpleasant surprises: the engine starts to run jerkily, some noise is heard in it after starting, and fuel consumption increases significantly. These are all signs of a clogged fuel filter that needs to be replaced. We will tell you how to replace it with your own hands in this article.

The fuel pump is broken, what should I do?

It is a very unpleasant moment when a fuel pump failure occurs, for example, on a highway or near a traffic light.

The situation becomes most tense at times of heavy traffic. If such a nuisance happens and there is no one to help, then the first thing you should do is roll the car off the roadway and try to “reanimate” the fuel pump.

Symptoms of a problem

In the arsenal of automotive tools of any caring driver there should be, along with the keys, a tester, even if in the form of a simple warning lamp and two wires.

The first sign of a malfunction on an injection engine is that the fuel pump motor is “silent” when the ignition is turned on. Accordingly, all attempts to start the engine in this case will not be successful.

In any unclear situation, remove the terminal. Very useful advice, by the way!

The driver will be very lucky if a very simple method helps, which should be taken first. To do this, remove the terminal from the battery for a while, and then put it back in and secure it. Perhaps the fuel pump will start working again.

Checking the power supply at the fuel pump terminals

Well, if this does not happen, continue to look for the problem. Here you should tinker and try to get to the pump itself, and use a tester or test lamp to check whether there is power at its terminals.

One end of the tester wire is installed on the car body - this will be “ground”, and the other - on the terminal connector of the fuel pump. If there is voltage, then, unfortunately, it is impossible to avoid replacing the electric motor, and if there is no voltage, the troubleshooting should be continued, already in the electrical circuit of the car.

The fuel pump screen is clogged

Not severe contamination of the filter mesh. It could be worse!

In this case, the engine starts, but does not develop full power.

Troubleshooting in an electrical circuit

The electric motor of the fuel pump rarely fails during normal operation.

Burnt contacts on the fuel pump

The main reason for this malfunction is the inexperience of the driver who does not monitor the fuel level in the gas tank, that is, when the fuel is almost completely gone. Gasoline pumps extremely do not like to work in the absence of fuel.

Sequencing

The car is installed on the inspection hole.
The interior opens and the right rear seat rises to an upright position. Underneath there is a layer of soundproofing material. He leans to the side.

The rear seat is raised, the sound insulation is removed, there is access to the cover

The cover is attached to 4 self-tapping screws, which can be unscrewed with a Phillips screwdriver.

The block with wires is disconnected manually, just lift the latch

This can be done conveniently with a 10mm socket socket.

These fittings are easy enough to squeeze with your fingers.

To remove it, loosen the bolt by 10 on the mounting bracket

Important points

Any work on the fuel system should be carried out either outdoors or in a well-ventilated area, away from sources of fire.
You need to carefully remove the old filter, since there is almost always gasoline left in it, which can get into the eyes of a person in the inspection hole.
A new filter must be installed in the direction of fuel flow. To do this, each filter has an arrow showing the direction of movement of gasoline.
When squeezing the plastic fittings when removing them from the filter, do not apply much force. Despite their apparent strength, they are very fragile.
The car's operating instructions recommend changing the filter every 30 thousand km. But taking into account the quality of domestic roads and gasoline, car service employees recommend changing the filter every 15 thousand km.

Replacing a fine filter is a task that is entirely within the capabilities of anyone who has at least once held a screwdriver and a socket wrench in their hands. The most important thing is not to forget to relieve the pressure in the fuel system, otherwise troubles cannot be avoided. And of course, we must not forget about safety precautions. All work must be carried out away from sources of fire, and work should only be done with gloves and safety glasses.
