Check your oil pressure switch.

Ditto. Probably needs replacing.

Re: fuel pump running with the ign off

I just replaced the oil sender, it has to be something in the wiring

I wish the problem was easy but I think I have to go into the harness

I was hoping that someone had a similar problem

thanks for the quick replies

Re: fuel pump running with the ign off

Unplug the switch and see if the fuel pump shuts off. If it does, you've got the wrong switch, or your new one is defective.
