ISO 33920-56B40 ECU, Mine's FUBAR. Anyone have one?
My buddy just bought a 1993 sidekick and the ECU is pretty close to beyond repair (holes in the PCB, many traces totally gone). I rebuilt it regardless and it now outputs code 12, but it seems the injector driver circuit is FUBAR -- there are no injector pulse or the 2-3 volts at the EUC even after cap replacement and rebuilding the damaged traces. If I can't find one in the next week or so, I'll attempt to replace the injector transistor(s) and refresh the associated solder connections but I honestly don't trust that board to not have issues.
I don't care if the ECU is rebuilt or has leaking caps, whatever you have. I can rebuild them, so I'll take it. PM me!
