Change to original PCM, sputtered for about 20-30 sec. then the same no start. Will hit a cylinder once in a while.
Check eng light on (computer responding)
Fuses ok, added another gallon of fresh fuel.
Could not easily get to the injection 3way connector so just used a "Noid" light, never flashed once. No signal to injectors.
Checked for crank reference signal at PCM (A/B connector, socket B-5). When cranking there was a constant 11.4v not the expected 1-7v varying signal.
Suspect circuit 430 short to power or bad crank sensor?
