My brother-in-law has a 1999 VW Passat 1.8l 20v with a bit of a problem, the other day whilst pulling out of his turning it just died.

It turns over but does'nt fire up, he called out the RAC and after them doing alot of funking about they came to the conclusion that it was broken!

They recon it has a fuel starvation, he has had the fuel filter changed just to eliminate it but still no joy.

He has been informed that the next port of call is the fuel pump fuse and then lastly the pump itself.

Question 1 :- Where is the fuse for the fuel pump?
Question 2 :- how hard is the fuel pump to remove and replace?

Any advise welcome.

MrBush

Anybody?

MrBush

He didnt take clip a kerb did he? is it possible it could be the emergency fuel cut off that needs reseting.

The fuel pump is most likely in the fuel tank. Lift the rear seat up and look for some sort of cover with wiring going through it. You should have battery volts going to it and an earth, check these whilst cranking (probably the two larger wires, there may be fuel gauge wires too).

If there's no live, suspect a fuse (check all of em to rule out stupid management ones!), main relay / fuel pump relay, broken wire or inertia switch.

If the pump is being powered, measure the resistance of it. If there is some, it's a good sign! If there isn't any, it's knacked! If you get continuity, rig up some wires so that you can connect an ammeter. When cranking you should get around a 5 amp draw. If it's less it's probably not pumping fuel, broken impeller or blocked pick up. If it's high, the pump could be seized or the fuel line blocked.

Thanks chaps for the advise!

It will give him something to be getting on with.....

Oh reguarding the fuel cut off switch......... where abouts would i be best looking for it?
