OK, old owner speaking here. First off the MAFS that was in there was a SOHC. You can’t use a DOHC one. Its either…SOHC, SR mafs, or Z32.

My guess is Mafs, if not a ground.

Go over the whole harness. Its probally gonna take alot of time but it was always that harness that gave me problems.

good luck sir
