Verifying the fuel pump

If the pump is not working properly, or there is a suspicion that it delivers insufficient amounts of fuel, then perform functional test of the pump in the following order:
- Check, responsible for operation of the pump, fuse number 18, located in the fuse box. It must be in good condition;
- Poddomkratte rear of the car and put it on the support;
- Ask the assistant to include ignition. In this fuel pump should turn that it must be accompanied by a characteristic sound. If the pump is working, then find the reason for which no fuel is supplied;
- Place a cloth on the end of the fuel line connections, and carefully remove the hose. This fuel should splash, ie The power supply system is under pressure. If so, then immediately put the hose;

- Disconnect the electrical connector of fuel level sensor and the fuel pump; connect to two external terminals of a voltmeter or test light on semiconductor diodes (Fig. 205);
- Switch on the ignition. The voltmeter should show the approximate voltage of the battery. If voltage is not present, determine the place of the electric circuit wire breakage and eliminate it;
- If the voltmeter shows pressure AB, remove the fuel level sensor and check whether the connected and whether good contact electrical wires between flange and fuel pump;
- If there is no breakage, replace the fuel pump;
- Install a new fuel pump and fuel level sensor, connect electrical wires.

Before changing the pump, check the pump relay to the service station.
