So guys I need help asap I need to fix this before I have to go to work on Monday. So the fuel pump will not stop running until I disconnect the battery. I found this issue because the pump must have been running all night and killed my new battery.

I am going to try to trace the issue right now, but hopefully you guys can think of something too.

Let me know and thanks in advance,

It sounds like the main fuel injection relay is welded shut. I'm assuming that this is a 240, and I don't know where it is, but it probably has two relays inside one case. I'd yank it, pull it apart and see if you can see one of the two contacts is not opening. On the 740 the relay always has power available to it regardless of the key switch position. So if it's closed, it will run the pump.

 

For the 240, the fuel pump relay is behind the glove box. It is usually white, about an inch square and 2-3 inches long, Just remove the felt cover underneath the glove box to access it.

 

yea it was the fuel pump relay, replaced it and sound stopped.

Thanks guys,
