Ok, I have a little issue I'm trying to resolve. There is a lot of information, so I will try to keep it organized. I hope.
Short:
I turn the Key. Power turns on. Fuel Pump will not turn on. Engine will not turn over with the key.
Long:
I turn the Key - Don't need help here, I think I have that down.
Power Turns on - Needed to replace the wiring harness. Most everything seems good now.
Fuel Pump will not turn on - I found that the problem is at the relay plug. It's not switching, although the relay is found to be good. As well as several other relays. Let me see if I can explain the problem. Picture a relay in your mind. Numbers 85 & 86 are used to actuate the relay (One Positive, and One Negative). Well both sides are receiving 12v power. (Both Positive) I traced the wires and the negative (Or what would be negative) goes to the ECU under Fuel Pump Relay Negative. Since I am receiving positive from this line, would it be safe to say that the ECU is bad? The wires trace correctly, I think. Dam, I gotta double check that. Any other ideas? Number 87 & 30 are correctly wired (Jumped, and the fuel pump turned on. Also tests good with a volt meter)
Engine will not turn over with the Key - This happened both before and after I replaced the harness. When I turn the Key to start, nothing. The previous owner changed the system to push button, but I was thinking about changing it back. (Might keep the Push button though) With replacing the harness, and making sure all the wires are correct. Still nothing. The wire is correctly connected at the starter relay, and the Ignition switch is new. I found the Green wire from the Ignition switch and there is no power going to it when the key is turned. Any ideas?
Hope I didn't confuse anyone.
