ECU Shuts off PLZ HELP.....

[bustiegtr]

Ok first off I recently did the Redtop swap into a 1991 nissan truck. I now have a problem the truck cranks but when I crank it the ECU(#63) shuts off. I have no idea why so I thought well let me try and run the wires directly to the battery and see if a constant charge would keep the computer on and nothing the ECU shuts off again. I am stuck now with no clue on what is going on. I talked to some other people about it and they said that I might have the Type X harness and the #63 ECU wont work with that harness. Well they sent me a pin diagram for the Type X and the plugs didnt match up so I guess I have the right harness for the redtop. I have ran power to the orange igniton wire on the ECU to atleast get that power too but nothing still turns off when cranked. Could my ECU be bad? I have no spark, no fuel, and no power to the ECU. Please any help would be great as this thing is driving me nuts!!!!!!!

Pull it out and put it back in 5 min later (resets the ecu) of that doesent work you might have a bad ecu.
