The good news: I got the fuel pump working.
The bad news: It keeps blowing the fuse. I am fairly certain that the pump not the problem. I think I have a short. I have checked the fuse panel and cleaned up all the contacts there. The main harness looks fine as it goes into the tunnel and comes out of the tunnel in the engine compartment. I have checked the wires coming off the main harness to the pump. The plug to the pump looks fine. From what I can see of it, the wires also look good behind the dash. I am thinking the short may be in the tunnel. Any specific ideas of where I should look for a short that I haven't looked for already? If it is the tunnel, is there any way to check for a short in there other than pulling the entire harness out? |

Pull the heater knob control and clean the ground, fan should stop running in off position. Hopefully it will help your other problem.

Get yourself the wire diagram on this site ........I think there is also one on the bird board and onein the Hayes book. I had this problem a couple of years ago and it was multiple issues. Cracked wires at the fuel pump and a bad pin connector at the harness to regulator plate. You need to eliminate each circuit first otherwise you will be chasing your tail. You could have different problems than I ............you need to systematically work each wire. Good luck |
