Folksvagen Sharan/Sharan repair>> System of injection of fuel of engine VR6>> The electric fuel pump>> Check of working capacity of the fuel pump If the pump badly works or there is a suspicion that it submits insufficient quantity of fuel inspect working capacity of the pump in a following order:
- Check up, responsible for pump work, a safety lock № 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 join that should be accompanied by a characteristic sound. If the pump works, find the reason on which fuel does not arrive;
- Put a rag on the connection end топливопровода, and cautiously 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 has not occurred, ask the assistant to scroll a starter the engine. In this case fuel should scatter from the removed hose;
- If it has not occurred, execute the following:
- Switch off ignition;
- Remove a rug on the right side under the second row of seats, turn away bolts of fastening and remove лючок an electrogasoline pump and the gauge of level of fuel;
- Disconnect штекерную колодку the gauge of level of fuel 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 pressure АБ. If pressure is not present, define under the electric scheme a place of a wire breakage and eliminate it;
- If the voltmeter shows pressure АБ remove the gauge of level of fuel and check up, whether are connected and whether have good contact electric wires between a flange and the fuel pump;
- If breakage is absent, replace the fuel pump;
- Establish the new fuel pump and the gauge of level of fuel, connect electric wires.
