Where does the power for the fuel pump goto? am i correct in saying its the black with red tracer
What does the Yellow with green tracer going to the ecu do?

I have no voltage on my fuel pump after doing various bits and bobs, but it is not being afected by my immobiliser.

Any help appreciated, cheers

Tony.

the fuel pump fuse is ok (15A 3rd up on the rh in fusebox) im tempted to run an ignition feed to a relay then to the pump but id rather sort the fault first

This is a better mod anyway as it keeps a constant 12v to the fuel pump at all times. As the wire's get old and cause volt drop. Before i did this mod i was only gettin 10.9v to the fuel pump. Hard wired it now and get a constant 13.5v at the pump splendid.

This is a commom mod on fuel injected cars that are getting on in the world

update:

If i bypass the fuelpump relay it runs,
Im not getting a spark as the coil has no supply, it sounds as if the ecu doesnt have power?

any ideas, i dont have the wiring diagram to trace as im at my parents.

Cheers Tony
