Hey. I have a 2.0 ltr 16v Redtop in my Corsa. The conversion got done not that long ago.
It's all of a sudden started over Fueling really bad.
I've found out that the fuel pump pleases itself and pumps petrol into the engine overnight. Even though the engine isn't on.
Why would it be doing this?
It's been to a few mechanics and they dont know what's wrong.
Any help would be much appreciated.

well instead of a switched positive(ignition) its wired on a permanent positive. find where the fuel pump relay is and see if the blue/red wire has had a permanent tapped onto it-if so put an ignition supply on
