GTI fuel pump and Relay

[chalky white]

Hi all,

Just been sorting through some issues with the 1991 Rivage (and there are a lot).

Can anyone confirm the following.

With the key in position one in ign, fuel pump kicks in and it's loud you can hear whiring away.

It continues to run untill I turn IGN on and it starts up.

from what I gather it should prime on IGN one and then shut off, untill you turn IGN on.

The difference is to do with the fuel pump relay, the 4 pin gives continuous pump run, the 5 pin primes and then cuts out until IGN starts and then it kicks back in.

Anyone know which one should be in the 1991 GTI.

Thanks

Hi,

Ignition on position 1 shouldn't do anything, AUX only.

Position 2 = Warning lights on and short prime from pump.

Then obviously turn over is on 3.

Either way the pump shouldn't run constantly unless the engine is being cranked or running, if it does then it could potentially be dangerous.

Although mine is an 83 tin top and yours is a 91 rag top, they both share the same DX Engine and therefore you should have the 5 pin Pump Relay (numbered as 2)

I had the same problem once with an incorrect relay.

Not long ago on my current car I replaced everything, wiring, fuse box, relays etc. 

Just went out to remind myself whats in mine. I have this now. (often used in later vehicles for speed limiters amongst other things)



Around £35 if you search by the part number

If you don't mind a little wait on the postage I found THIS for you for half the price

This came in from Turkey in a couple of days.
So no messing about waiting.
Anway, I have realised the issue, as these cars have 2 fuel pumps, the in tank lift pump is squeuling like mad and I now understand that it is not the main pump under the car body.

The fuse blowing and heat generated is because of the supply being drawn to the lift pump.
What can happen is the pump starts to fail or it's overworked due to clogged filter in the tank or the fuel filter in the engine bay.

I have now ordered a new pump so will have a look see what condition the tank is in and get my magnet out to fish out any metal bits. Then it's line cleaning time and new filter.

cheers

Well that sucks. Thanks for keeping us posted.

I'm surprised mines all OK after standing for years and it's a good job too, I really cant be bothered with an issue like this right now, got enough to do.
