2 gsf ones (worked for a few times now wont unless i hold contacts shut)
and the original one, which has worked but its as if the contacts were stuck shut as he pump would buzz constantly however that wont work now either unless i hold contacts shut.

Hey that's a great thread, very helpful. It's got to worth doing that anyway, maintenance wise.
Cheers for that and thanks to Chudd for posting the OP.

Mine was full of tiny rust particles too.
No wonder the pump was working hard and drawing too much current.

if i were to put a 16v kr engine in on carbs
would i use a different fuel pump like a facet or something and would that mean id bypass my old pump and relay? or could i? as thats the route i want to go down so might be easier

Just wondering why it's not blowing fuses.
Have you disassembled a relay to see what the failure is?

I'd be inclined to test the supposed failed relays by probing the switch contacts, and seeing if it works on the bench.
check the contacts in the fusebox too, incase there's a poor connection there.

Later cars had the five pin relay fitted.

I doubt all these relays are blowing, its more likely the fusebox has poor contacts or there is a problem with the rev counter feed from the coil. do you definitly have spark when this problem occurs, because if not the relay wont do anything
30 - permanent live
15 - ignition live
31 - earth
31b - rev counter feed (pulsed earth)
87 - output to fuel pump

tested the relay outside the car and it does absolutley nothing.
the car definatley has a spark like i say if i hold contactas shut on relay the pump works and car runs until i let go of relay lol
no visable components blown on relay looks brand spanking still!
im worried about getting another relay just in case i blow this one too! could it just be the gsf relays are utter toss?! (should i try another vw relay or is there one from another car i can try ?
