On any passenger car with gasoline engine, the fuel pump serves to supply fuel under the pressure from the fuel tank to the dosing device - depending on the modification of the motor on the VAZ machines, the fuel system may be carburetor or injection.
The VAZ 2110 benzonasos is mechanical or electric, its type depends on the type of fuel system installed on the engine.
Baszonasos (BN) on carburetor-activated carves AUTO 2110 is located behind the valve cover, next to the interrupter-distributor, on a car with an injection engine, it is in the fuel tank (submersible type). If BN begins to give failures, the motor does not pull and does not develop turnover, but in many cases the engine does not turn out at all.
Scheme of fuel pump (electric)
The device itself of the electrical displacement 2110 is sufficiently simple - the node is an electric motor to which 12 volt power is supplied. The BN is mounted in the housing, the mesh is installed on its input - a coarse filter. The filter element does not give dirt particles to penetrate into the pump housing, thereby preventing a device from clogging and a possible breakage.
The following elements are present in the electric flow chain pump of VAZ:
- ignition;
- fuse;
- relay;
- wiring;
- the engine control unit.
When turning the ignition key through the relay, food is supplied to the BN terminals, and the pump begins to swing gasoline. After the fuel input line was filled with gasoline, the computer (control unit) via the relay gives the command to turn off the voltage - the fuel system is ready to start the engine, only the motor remains to scroll through the starter. 
Fuel pump relay VAZ 2110
The relay in any electrical circuit is intended for closing and opening the chain, its main role is to protect the elements of the electrical circuit from a large start current. When you start the DVS current required for the starter scrolling, reaches 80-300 amps, and if the relay is not installed, any element of the electrical circuit may suffer.
The fuel pump relay VAZ 2110 is a standard type, inside the plastic case there is an electromagnetic coil with a core, when the voltage is submitted due to the electromagnetic field, contacts are closed. Relay 2110 - four-contact, calculated for a current of 30 amps.
Where is the fuel pump relay VAZ 2110 injector
Often due to the failure of the relay, the engine stops run to eliminate the problem, it is necessary to replace the faulty part. Baszonasos (RB) relay VAZ 2110 Injector is located in the cabin of the car, under the instrument panel, next to the central console. To get to the Republic of Belarus, you need to unscrew two screws of protective plastic casing, to dismantle it - from three elements of the "Relyness" elements here, which is responsible for the operation of the pump, will be located in the center (in the figure below at number 5). 
Fuel pump VAZ 2110 Injector Price
Electrical displacements 2110 are produced by various manufacturers, can be sold both assembly with the case and separately the electromotors themselves. In collecting BN, it makes sense to change only when the flask (body) of the device is damaged, only the replacement is required only by the fuel pump motor itself, since it mainly ceases to work.
Basic gas station producers 2110-2112:
- Weber;
- Hofer (Germany);
- Bosch;
- SEPO (Saratov);
- Pekar (Russia).
In fuel pumps VAZ 2110 injector costs can be different, on average BN can be bought at a price of 700 to 4500 rubles. The most inexpensive production of HOFER and the bakery production, the average price of the electric junction (motor) assembled with the PEKAR mesh filter - about 800 rubles. BN company BOSCH is the most expensive, the cost of the device assembly is 4300-4600 rubles.
Replacing the gasoline pump mesh VAZ 2110 Injector
Russian fuel does not always meet the requirements of quality, and over time, due to poor gasoline, dirt is accumulated in the gas tank. SOR also scores the filter-grid of the electrical space, due to the accumulated dirt, the fuel does not fully enter the fuel line, interruptions occur in the operation. To troubleshoot a malfunction, you need to clean or replace a coarse filter, but to get to the mesh, you need to shoot BN.
Before you begin the disassembly, the pressure in the fuel system should be reduced, otherwise the gasoline can break through the gasoline fueling fittings and pour the entire interior of the car. For pressure booming, we take out the fuse that is responsible for the work of BN, run the motor and wait until it stalls. Replacement of gas station grid VAZ 2110 Injector We produce as follows:
If the pump stopped working, there can be several causes of the fault:
- wiring is damaged;
- burned fuse;
- relay stopped working;
- bN motor burned;
- the engine control unit has failed.
When the driver on a car with an injection engine VAZ 2110-12 includes ignition, the electric motor starts to work - a characteristic buzz is heard. If no sounds are noted, it means that BN does not pump bn.
The easiest way to check the fuse of the electrical space, which is almost there, where the relay is located on the left of the Republic of Belarus. 
If the fuse burned, it must be changed. It often happens that when replacing the fuse immediately burns out. The main causes of such a phenomenon are:
- "Korotit" itself fuel pump;
- there is a closure in the wiring.
Another characteristic malfunction of the electrical space - the fuel injection occurs, but the work is accompanied by a strong noise. Noisy benzonasos - a sure sign that this device will not "live for a long time", and in a short time it fails.
How to check the relay
If the electrical displacement when the ignition is turned on, it does not submit any signs of life, it does not mean exactly what he burned down. The cause of the malfunction can also be a relay. The easiest way to check the RB on the rumor - when switching on the ignition, the relay should click. If the click is not audible, the most likelihood that the "Relyushka" is faulty.
But not everything is so simple - the problem can be "cunning", for example, the car starts not the first time. The cause of the malfunction can be hidden in the burnt contacts of the relay. Check the performance of the pump itself is quite simple, we do as follows:
If there is no voltage on the RB on the RB on any of the contacts, you should search for a break in the wiring, there may still be bad contact at the place of fixing the wires with the terminal.
Fuel check valve
The electric belt of the VAZ "Dozens" has good performance, but it creates too much pressure in the fuel system. In order to put pressure in the norm, the VAZ 2110 gas station valve is embedded in the fuel line, it is in the "output" BN hull fitting. The "dozens" also establishes the pressure regulator, which is located behind the fuel ramp. 
The valve fault is to stick the ball in the open position, and the fuel pressure in the system can be discharged to zero. If such a problem arises, the car is very badly started, since all gasoline from the fuel lines when the ignition is turned off goes back to the benzobac. Is it really possible to repair the valve?
Machine drivers 2110 claim that you can try to knock on the stacker in the BN flask so that the shut-off ball gets into its place. If this method fails to eliminate the fault, it is required to replace the flask of the electrical space, since this body itself is unimprovable.
The car VAZ 2110 (LADA-110) was made on AvtoVAZ since 1995, and the first motors on this model were with carburetors. Eight-flaped VAZ 2110 windows with a capacity of 72 liters. from. They were put on the "dozens" until the year 2000, and the fuel pumps on these DVS, respectively, were mechanical.
The fuel mechanical pump 2110 consists of parts:
- metal housing (two half);
- top cover;
- pusher with a diaphragm;
- two valves;
- return spring.
The gasoline injection of fuel tank is due to the oscillations of the aperture, opening and closing valves. The motion of the diaphragm with the pusher is driven from the Eccentric of the camshaft, on the lower body BN there is a lever of a manual pumping of gasoline. 
Malfunctions of mechanical benzonasosa
All parts of the automotive motor are subject to wear and aging, and in time, resource is also produced in mechanical BN. Main malfunctions of a mechanical device:
- corpoxing;
- cracking of the diaphragm;
- valve breaks.
If the diaphragm passes the air, the pump can stop pumping gasoline into the carburetor, the fuel falls into the crankcase and mixed with engine oil through the torn membrane. When gasoline gets into oil, fuel consumption increases sharply, and the engine itself is badly started, especially in a heated state. Check for gasoline in the crankcase is simple enough - if the oil probe is aligned with a lighter, there will be a fire, and a gasoline smell will go from the oil crankcase.
A frequent defect occurring in mechanical fuel pumps is the surface of the surface at the place of fastening a b / pump to the housing of the auxiliary aggregates. If the surface is deformed, the engine oil begins in the junction between the planes.
Fuel pump VAZ 2110 carburetor Price
Unlike electrical traps, mechanical BN is mainly cheaper, the price largely depends on the manufacturer. The most famous companies producing fuel pumps:
- Baker;
- DAAZ.
The cost of the device is between 350 to 850 rubles, also on mechanical b / pumps are sold Repair kits, a diaphragm, rod, valve is present in the set. Remkomplekt is fairly cheap - from 70 to 200 rubles, but it does not always make sense to repair, as the pump itself assembled inexpensive.
Interesting the fact that fuel pump for carburetor engines on the "top ten" VAZ is suitable from the VAZ models 2108-09-099, as well as from "Zhiguli" VAZ classic 2101-07. The "classic" BN differs only by a few other location of fuel fittings, and to install the pump from the "classics" on the auto 2110, it is necessary to use longer fuel hoses.
