Hey guys, Im not one to bother you guys with what seems to be such a simple trace and find problem. I have read many of threads with similar issues to no avail. I could really use your help.
I have an 89 supra that i swapped a motor in from a 92. Got everything wired up, bolted up, and drove the car for a day putting on about 60 miles. On my way home at steady throttle around 65 mph the motor without warning shut down. It will turn over freely but will not fire.
I have come to the conclusion, that i have lost power to my fuel pump, and I think ECU. I am getting power to Ign Sw and +B1, but i am not getting power to Batt, +B, and M-Rel, as well as no check engine light.
I have and will continue to check fuses, relays, grounds, and connections, The main thing I am asking help with from you guys is Tracing the path of power from the battery to the ECU. I believe from all my reading that the lack of power to Batt, +B, and M-Rel pins means i am losing the 12v before the ECU, but please correct me if I am wrong. I cannot for the life of me read the TSRM wiring diagrams and could really use a simple description of where the power starts, stops, and passes through before reaching the ECU.
Any help is appreciated, cheers!
