If the pump badly works or there is a suspicion that it submits insufficient amount of fuel, inspect operability of the pump in the following order:

- check, responsible for operation of the pump, the safety lock No. 18 being in the block of safety locks. It should be in good repair;

- поддомкратьте a back part of the car also put it on support;

- ask the assistant to include ignition. Thus the fuel pump should turn on that should be accompanied by a characteristic sound. If the pump works, find the reason on which fuel does not arrive;

- put a rag for the connection end топливопровода, and carefully remove a hose. Thus fuel should scatter, i.e. the power supply system is under pressure. If it so, at once put on a hose;

- if it did not occur, ask the assistant to scroll a starter the engine. In this case fuel should scatter from the removed hose;

- if it did not occur, execute the following:

- switch off ignition;

- remove a rug on the right side under the second row of seats, unscrew bolts of fastening and remove the electrogasoline pump and fuel level sensor hatch;

- disconnect a shtekerny block of the fuel level sensor and the fuel pump; attach to two external plugs the voltmeter or a control lamp on semi-conductor diodes (fig. 205) ;

- include ignition. The voltmeter should show approximate tension of AB. If tension is not present, determine by an electric circuit a place of a wire breakage and eliminate it;

- if the voltmeter shows tension of AB, remove the fuel level sensor and check, whether are connected and whether have good contact electric wires between a flange and the fuel pump;

- if break is absent, replace the fuel pump;

- establish the new fuel pump and the fuel level sensor, connect electric wires.

Note Before changing the pump, it is necessary to check on HUNDRED relays of the pump.
