Hi,
Anytime there are wiring issues, it's a mess. LOL Regardless, I attached the wiring schematic for the powertrain control circuits. The fuel pump is integral.
I highlighted anything that is related to the pump so that you can find it easier. I was going to highlight all the wiring, but when I did that, it became a mess. (Too many wires powering different things).
Take a look through them and let me know if they help. Also, note that it was three pages long, but I had to cut each page in half to make them readable for you. I did overlap them, so you can follow from one to the next.
Let me know if this helps or if you have other questions.
Take care,
Joe
