I'm having some crazy electrical issues with my build. I picked up the car as a shell in March. It was FWD.
We did the AWD conversion, fuel senders rewired as the diagrams on here suggest, etc.
We got the motor in the car and yesterday went to connect the laptop to test the fuel pump. Two separate laptops would not connect. We also noticed the MFI/Pump relay was not clicking so we tried jumping the relay and the fuel pump kicked on although still the laptops would not connect. This morning we went to the local pick and pull and grabbed two replacement relays for the car, hooked them up and still have the same results. No ECU power, No turn over, No fuel pump turn on. The relay works and you can hear it click but the only way the pump kicks on is if you jump the relay.
There is no voltage coming from Pin 12 and 25 on connector B-53 (Power Supply) even after swapping in the new relays. We tried my 95 Eprom with DSMlink V3 installed and then the 97 ECU that was in the car so we don't think it is an ECU problem.
Also I noticed when you turn the key on the odometer goes up without the car even running or moving yet. There must be a short somewhere, but I'm not sure where to begin. Does the odometer tie into the engine harness somewhere and causing the other problems? Please someone help.
