If I remember right mine was so corroded it actually fell apart. I cut the whole thing out and put a in-line replaceable fuse in its place. do you have some kind of a jumper wire

 

Just test voltage on both sides of the link - it should be the same.

 

O.K I put a jumper wire from the A to B ports on the ALDL plug. According to the service engine flashes I have a code 12 and a code 54. I have no idea what this means but hopefully someone can help me out.
Also I ran 12v into the G port (fuel pump) on the ALDL and the pump did turn on.

 

Code 12 is usually the first code you get and just ignore it.Watch the code after code 12, that's what you need.

So I have a code 54 egr system failure or fuel pump circuit low voltage. How would I go about fixing this? I just want my fuel pump to work lol.

 

I grounded out my test light and according to that I have NO power coming to wires in the fuel pump relay part of the harness with or without the key on engine off. The ground is good but no power to the remaining parts of the connector.

 

I found it!!!!!!!!!!!!!!! The orange wire going into the fuel pump relay had a tiny pinhole about ¼ before the plastic connector. The wire was corroded to the point where it was just green dust a good 3in into the harness and where it connected to the metal terminal inside the connector. I jerry rigged a new wire in place and everything run as it should.
Now for the final (hopefully) question. Where can I get a new metal connector tab that snaps into the plastic housing of the fuel pump relay connector part of the wiring harness?
