Message I have a 90 NA MT that I recently purchased in Nov 19'. Car did not run when purchased. We decided to rebuild it and replace what we can. Short Block was cleaned and good. Heads where cleaned and rebuilt with new valves but reused cams. Replaced timing belt, new fuel injectors, new fuel rails, new FPR, new plugs and coils. New wiring specialities harness. Programmed ECU from Z1, New accessories (starter, alternator, ps, and ac). Mostly everything was replaced and follow to specs from FSM.

When the maf is plugged in, it'll crank, turn over and die. When the maf is unplugged, it'll idle but very low RPMs, like 250-500.

Replaced MAF to rule that out but same problem is persistent. We have not replaced the PTU, CAS or TPS.

I wanted to ask here before I gave up and send it to a shop.
