I will try to collect all the information available at the moment.
The hatch for access to the fuel pump from the passenger compartment is made in order to be able to repair, replace and diagnose the fuel pump and other elements of the fuel system in the tank without removing the fuel tank. In the standard version, this can only be done by removing the tank, and removing it with gasoline is not the most pleasant / cheap pleasure. Those. in fact, if the fuel pump malfunctions, you can buy a fuel pump from the VAZ 2110 in any village and replace it and continue to drive quietly.
Moreover, on some very solid cars of other brands, hatches are already made at the factory, here are examples: A hatch for accessing the fuel pump from the passenger compartment. (P) (post #18084660)
Advantages:
1. It is possible to replace/repair the fuel pump, fuel gauge and other elements of the fuel system without removing the tank. Added on 08/17/2013 Incl. essentially in the open field. You will only need to buy a turbine in the nearest store. Here is an example from life: A hatch for accessing the fuel pump from the passenger compartment. (P) (post #14418759)
2. You can see firsthand how the fuel system in the tank functions. Example: Pressure in the fuel line, rail (message #10080584) And try to do it somehow differently!
2.1 You can check the voltage at the connector that goes to the fuel pump at the time of the problem and make an assumption that the problem is in the fuel pump or in the electrician. (added 04/13/2011)
3. Feel the smell of gasoline in the cabin if gasoline starts to ooze through the fuel pump cover. If everything is working properly, then there will be no smell of gasoline in the cabin. Tested by many teammates.
4. Change the fuel pump 4 times a day. With the removal of the tank, such a trick will not work. I had to do this until I realized that gasoline was leaving. see point 2
Additionally: Removing the tank does not give any advantages compared to the hole.

Flaws:
1. The rigidity of the body may be broken. Very debatable. There is no evidence. There are also no examples.
2. Corrosion is possible in the place of the cut hatch. Personally, I have not a hint for 2 years.
2. The smell of gasoline in the cabin is possible. see item 3 Advantages.
3. You can cut yourself on the edges of the beam when unscrewing the fuel pump cover. See ways to unscrew the fuel pump cover. Skillfully, it is possible and not to do such a thing.

Every car owner can face a situation when the Chevrolet Cruze does not start, despite the fact that the starter turns well and there is no clatter sound that retracts the relay.

The reason for this is that the fuel pump is not working. The module does not pump gasoline into the fuel line.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

Article and price of the fuel pump

According to the reviews of car owners, the fuel pump does not cause problems for Chevrolet Cruze drivers with both 1.6 and 1.8 liter engines. Despite this, there are times when a node fails. Its maintainability is low, so replacement is required.

The Chevrolet Cruze has a General Motors pump. It is impossible to find the original fuel pump for sale. You can only purchase a full cup of the fine filter assembly. Its article is GM 135 772 30. The price for a fuel module ranges from 36,000 to 40,000 rubles.

It is very difficult to find an analogue of the original fuel pump, especially for 2012 models. Many car owners prefer to install a BOSCH pump assembly on their Chevrolet. Its article number is 0 445 010 332. Unlike the original, the price for BOSCH starts at 10,000 rubles.

For the above reasons, many car owners are trying to find the most similar fuel pump for their car. Most non-original products are higher than regular ones.

According to the reviews of car owners, good interchangeability of the Chevrolet Cruze pump is present with the following cars:

Aster;
Nexia;

Required Tools

In order to repair the fuel pump, the car owner will need the tools that are listed in the table.

The process of replacing a gasoline pump is accompanied by work with places that are significantly affected by the external environment, so many elements turn out to be heavily contaminated. To clean them, it is recommended to use rags and brushes.

Replacing the fuel pump on a Chevrolet Cruze

The failure of the fuel pump does not allow the power plant to develop its power of 140 or 109 hp. Loss of dynamics by the machine is not the only problem. The car may completely stop starting. There is only one way out of the situation - to replace the failed node.

In order to dismantle the fuel pump in a Chevrolet Cruze, you need to completely remove the fuel tank, since a special hatch in the cabin under the rear seats is not provided by the car manufacturer. It is recommended to carry out work with an assistant, since it will be very difficult to disconnect the tank alone. In order to facilitate the removal of the fuel pump, the owner must take care in advance that there is as little fuel as possible in the tank. To dismantle the pump on the Chevrolet Cruze, you need to refer to the instructions below.

The vehicle's fuel system must be completely depressurized. To do this, you need to start the car and pull out the fuse with the number 20, which is shown in the photo below. When the machine stalls, you can proceed to further work.

Jack up the right side of the car. When removing the tank, this will help the machine keep its balance.

Remove the fuel filler clamps with a screwdriver, as shown in the photo below. It is recommended to put all fasteners in a separate box so that there are no difficulties during installation due to loss of parts.

Remove the bolt securing the clamps that hold the gas tank.

While holding the tank, dismantle the clamps. For these purposes, it is advisable to use the help of a partner. He has to hold the gas tank. Otherwise, there is a risk of damage to any element of the fuel system.

Carefully lower the tank and unhook the remaining tubes with wires from it.

It is recommended to clean the hatch before removing the module. This will help keep dirt and dust out of the tank. Using a hammer and a small metal blunt nail, unscrew the cap clockwise as shown in the photo below.

Gently, without sudden movements, pull out the fuel system filter, which is located inside the gas tank. Its dismantling is accompanied by the risk of damage to the float, which can cause incorrect operation of the gasoline level sensor.

Press the latches as shown in the photo and disconnect the retaining rings.

Remove wires, hose, connectors and fuel level regulator.
Carefully remove the fuel pump from the filter cup. It is mounted on three axes, so there is a risk of damage to its body or mounts.

Remove the mesh and visually inspect it. If the mesh is very dirty, you can clean it with cleaning products or replace it with a new one. When installed, it must be dry and clean. A contaminated mesh can cause an unstable supply of gasoline to the fuel line. Because of this, there is a high risk of interruptions in the operation of the power plant.

Remove the fuel pump from the filter housing.

Install the new fuel pump in place of the old one and assemble everything in the reverse order.

After installing the fuel pump, it is necessary to start the engine and check the operation of the power unit. During the test run, the fuel system must ensure an uninterrupted supply of fuel to the combustion chamber. Otherwise, the correct installation of the pump must be checked.

Hello! On your site I found instructions for replacing the Chevrolet Cruze fuel pump mesh filter. Please clarify, does the Cruze have a fuel pump hatch under the rear seat? (Eugene)

Hello Eugene. Thank you for your attention. In the Chevrolet Cruze, the fuel pump hatch is missing under the rear seat. To replace the fuel filter, it will be necessary to dismantle the tank.

Replacing TF in Cruze

First you need to relieve the pressure in the system. To do this, start the engine, then remove the fuel pump fuse, wait a bit until the car stalls. To make it more convenient to remove the tank, the right side of the vehicle must be jacked up, in particular, the rear wheel. It is not necessary to dismantle it.
Now let's start removing the tank itself. To do this, unscrew the fuel filler clamps and unscrew the screws of these clamps. Support the gas tank while unscrewing. You will need the help of another person to dismantle the steel clamps. The clamps need to be slightly lifted, and then brought out through the loops.
Further, having slightly lowered the gas tank, disconnect all hoses and pipes, as well as wires, from it. So you can completely dismantle the tank.
Now you will need to dismantle the ring with which the gasoline glass is attached. To unscrew it, you may need a hammer, the glass will have to be knocked out counterclockwise.
After dismantling the glass, slightly press it, and then dismantle the retaining rings.
Remove all unnecessary items, in particular the sensor, wiring and other connectors.
The fuel pump itself is installed in a glass, you will need to get it.
After dismantling the pump, it must be disassembled. The filter mesh is located inside the device. In principle, the parsing procedure is not particularly complicated, you can sort it out on the spot.

Hello! P10E2, B3FOO - what do these error codes mean? Nissan Teana 2008, 2.5 vol. (Sadyr)

Hello Sadyr. Unfortunately, we cannot solve your question, since we do not have a database for self-diagnosis error codes. Such a problem, in particular, with error b3f00, is known to many Teana car owners. We can recommend that you decipher the codes yourself using the AutoHex II program.

If you monitor the Internet, you can understand that the owners of these cars write in their reviews that this utility (if it is updated) contains these combinations in its database. If you try to download and decrypt them in this way, you will probably understand what the point is. You can also try to decipher the errors in OBD mode - this way we will most likely be able to decipher the combinations and try to help you.

Video "Nissan car diagnostics"

On the example of a Nissan Tiida car, you can familiarize yourself with the diagnostic process using an adapter (the author of the video is nikvak37 11uu0276).

This is not about a compact hatchback, which is a complete copy of the Suzuki Ignis, but about the original development of General Motors. Over the long years of production, the Chevrolet Cruze has been aggregated with both gasoline engines and diesel hearts. Nevertheless, cars with gasoline engines of 1.6 and 1.8 liters have become widespread. It is on their example that we consider the replacement of the fuel filter.

How often do you need to replace?

General Motors only specifies drain intervals for Chevrolet Cruze diesel models. The fuel filter must be replaced every 60,000 km or every 2 years, but for the long life of the Common Rail system, it is better to reduce the frequency of replacing the fuel filter for fine fuel cleaning to 15 thousand km.

On both gasoline and diesel engines, a clogged fuel filter can be recognized by the following symptoms:

difficult engine start;
failures during sharp acceleration from low revs (even short-term trimming is possible);
overall loss of dynamic performance.

Choosing a fuel filter on a Chevrolet Cruze

The power supply system of gasoline units does not have a removable fine filter (it is tightly built into the fuel module and can only be changed when assembled with the fuel section). The filter element in front of the fuel pump also protects the system from the ingress of dirt particles, but even it cannot be replaced separately.

Some Chevrolet Cruze owners get out of the situation by choosing a fuel pump from Opel Astra (not similar to the original one, so it will have to be slightly modified before installation). Since the manufacturer does not regulate the frequency of installing a new gas pump mesh, the original article number for this part is not provided as such. You can buy only the fuel module assembly.

Replacing the Chevrolet Cruze fuel filter with your own hands is possible only in a barbaric way and using analogues (for example, Delphi HDF623). Therefore, it is in our power to demonstrate the method of complete replacement of the fuel module and gasoline pump assembly with a coarse filter.

In the case of diesel engines 1.7 and 2.0 TD, on which the CR system is extremely sensitive to fuel quality, only original filter elements should be installed.

Removing the tank

The TF on the Chevrolet Cruze is located in the fuel tank. The design feature of this car is that there is no technological hatch under the rear seat cushion for access to the fuel section. To replace the fuel filter, you will have to remove the tank from the car, so it is in your interest that at the time of repair it contains no more than 10-15 liters of gasoline. It is most convenient to change the TF yourself from the viewing hole, otherwise the aft part of the car will have to be quite strongly lifted and fixed on the stops.

Before starting the replacement, it is necessary to empty the fuel line. To do this, just start the engine, and then pull out the fusible link of the fuel pump (fuse F20 of the mounting block in the engine compartment). Lack of gasoline pressure in the line will soon cause the engine to stop.

To remove the tank you need:

unscrew the fuel filler clamp with a slotted screwdriver;

unscrew the 2 screws securing the retaining plates. After unscrewing, holding the tank with your hands is quite problematic, since an assistant will be required to dismantle the plates. If you work alone, use a jack as a support for the tank;

remove the retaining plates (they need to be pushed forward a little to get them out of the grooves);

Disconnect the fuel supply and return fuel lines, tank ventilation line. Initially, you need to remove all hoses in places where, after leaving the tank, they join with counterparts under the bottom of the car. The hoses have snap-on connections. In order to subsequently assemble everything correctly, even during dismantling, mark the gasoline supply or return drain pipe and the corresponding connector.

lower the tank slightly to gain access to the power plug;
after removing the chip and releasing the harness from the retaining latch, the tank can be completely dismantled.

Chevrolet Cruze fuel filter replacement

Remove the hose from the top of the fuel module.
The fuel section is held by a thrust plate. Using a hammer and impact screwdriver, move it counterclockwise until the plate comes out of the slots.

Dismantle the plate and, if possible, clean the repair area from dirt.
Pull out the fuel section. It will take some dexterity to drain the maximum fuel from the glass and not break the FLS float.
Disconnect power connectors.

As owner reports show, there are 2 types of fuel sections on the Chevrolet Cruze. To remove the pump, you must remove the retaining rings. The fuel pump sits tightly on three vertical axes. As practice shows, when removing them it is very easy to break, so it is necessary to acquire fasteners of similar length and diameter in advance.

After removing the fuel pump, you can assess the condition of the mesh, if necessary, rinse it or replace the assembly with a new fuel pump assembly with a filter element.

Having replaced the fuel filter on the Chevrolet Cruze on your own and assembling all the nodes back, turn it on several times for 5-10 seconds. ignition. The fuel pump will fill the line with fuel, after which a test run can be made.
