its wired up wrong

quarter pounder · 09-06-2008, 06:29 PM

but the pump or wiring hasn't been touched.

paterson02 · 09-06-2008, 06:50 PM

pinched wire?
its obvously getting constant power in the wiring from a source somewhere or problem with the ignition switch from wear wat did you last change before this started happining
sorry for the short reply before but when people change a pump then complain it's usually there own mistake and thats what i thought had happened.

Yeah the pump and wiring is original.
Another engine has been fitted recently, but this problem only appeared today.
Wasn't doing it yesterday. It's got me buggered.

Yeah right, problem solved for a week or so, then it started again.
The actual problem was in the oil pressure switch, which apparently controls the fuel pump after start-up.
This is because in the event of an accident, the engine stalls, no oil pressure, the fuel pump stops too.
Don't know if you guys were aware of this one or not, but something to watch/check for if it happens to you.

Cheers.
