The fuel pump is faulty Try to start the engine with the new fuel pump and, if necessary, replace the pump. Check and, if necessary, adjust frequency of rotation of a cranked shaft of the engine idling
Frequency of rotation of a cranked shaft idling wrong, rough or unstable The hose of supply of fuel from the fuel filter to the fuel pump is not tight Reliably fix a hose
Air in fuel system Remove air from fuel system
Insufficient supply of fuel in connection with pollution of the fuel filter or a tube of return of fuel, leak from a tube of supply of fuel to a nozzle, an excess of a tube or perezhatiy connections of tubes Examine and, if necessary, replace tubes and hoses or replace the fuel filter
The nozzle is faulty Check and, if necessary, replace a nozzle
The moment of injection of fuel is incorrectly adjusted Adjust the moment of injection of fuel
The mechanical part of the engine is faulty Check a compression and, if necessary, repair the engine
The fuel pump is faulty Try to start the engine with the new fuel pump and, if necessary, replace the pump. Check and, if necessary, adjust frequency of rotation of a cranked shaft of the engine idling
Engine overload at movement on high transfer Observe the correct speeds of movement
Smoky exhaust (black, dark blue or white color) The engine does not get warm to normal working temperature Check and, if necessary, replace the thermostat of system of cooling
Inappropriate maximum frequency of rotation of a cranked shaft of the engine Check and, if necessary, replace the fuel pump
Sprays of nozzles are faulty Check and, if necessary, repair or replace fuel nozzles
The moment of injection of fuel is incorrectly adjusted Adjust the moment of injection of fuel
Capacity of system of production of the fulfilled gases is limited Check system of production of the fulfilled gases on lack of dents
The mechanical part of the engine is faulty Check a compression and, if necessary, repair the engine
The fuel pump is faulty Try to start the engine with the new fuel pump and, if necessary, replace the pump. Check and, if necessary, adjust frequency of rotation of a cranked shaft of the engine idling
The engine capacity, insufficient acceleration of the car (the speedometer is serviceable, coupling does not slip) is reduced Inappropriate maximum frequency of rotation of a cranked shaft of the engine Check and, if necessary, replace the fuel pump
The air filter is polluted Clear or replace the air filter
Insufficient supply of fuel in connection with pollution of the fuel filter or a tube of return of fuel, leak from a tube of supply of fuel to a nozzle, an excess of a tube or perezhatiy connections of tubes Examine and, if necessary, replace tubes and hoses or replace the fuel filter

Search and elimination of malfunctions of a fuel tank and топливопроводов

Sign
Probable cause
Elimination method
Unstable operation of the engine because of insufficient supply of fuel Will bend a gasoline pipe line or a hose of supply of fuel Replace or repair
The hose of supply of fuel is polluted Clear or replace
The fuel filter is polluted Replace the filter
