I Checked the ecm harness last week and found the red/black had been been spliced before. After messing with the harness the car started later that day. IThe next day I had a scan done. After clearing all of the codes the one that returned was the communication to the ECM code remained. Today I was going to fix the red/black wire and it would not start again. I fixed the wire and still does not start. I do not here the fuel pump. There is 12 volts on the red/black wire. I'm trying to find wiring diagrams so I can check ground wires.

It’s all wrapped up now. I used good environmental splices. There was also a green and black twisted pair that look like someone had tried to fix at some point. I redid one of those as well.
Customer reply replied 4 months ago
There is 12 volts on that wire. It’s looks solid when I move the harness around. Is there any grounds I should check?
Customer reply replied 4 months ago
I got it figure out. I found that the black/grey wire going to the relay was also bad.

nice !! glad to hear !!
