As described in the title, my fuel pump is constantly on from the moment i turn the key (i.e. never stops priming).
I have checked the system for leaks, including injectors stuck open, and can find nothing.
Anyone come across this issue before?
If there's no other logical reason why it's doing this, I'm thinking the previous owner may have hot wired the fuel pump straght to the ignition for some reason.
Though I'm struggling to think of what this could be masking!
The previous owner had bypassed the headlighter adjuster circuit, and also placed a bypass wire from a pin on the 'engine' relay straight to the chassis / -ve (and for some reason the coils wont spark without this bodge!) - so I dont doubt theres a chance he's screwed with the fuel pump electrics too.
I was going to look at the relay, and whether it was stuck on there - but don't know where it is!
The box in the engine bay names the fuel pump fuse, but not the relay.
Anyone know where it's hiding?
As mentioned, I'm getting terrible MPG, so dont think it'll pass the MOT at this rate
Any help is much appreciated!
Thanks
