Well all you need is fuel, compression, spark and all timed right = bang. Your missing one of those.
If original coil you might want to try there.
Do you have good spark at the plug?

What does your baro read?

Put a new distributor in it yesterday, only had 2v return signal. Bent metal for pickup.
Almost started then back to what it was doing.
Has great spark. Noid lights say the injectors are firing. Plus you can smell the fuel.
Timing is dead on. Good compression.
Baffled, been a mechanical for 30+ years. Missing something.

40 psi at fuel rail. Cleaned injectors, almost started again.
Will the temp sender cause this ? Seems to test ok. 5v in and 1v+ out.

I now have two codes actually one code 0320 it says ignition distributor engine speed input and if I go to OEM enhanced it tells me the same code but it says cranks position sensor which is brand new and I wouldn't have spark if it was bad.

The return signal from the distributor is not always 5 volts it drops off to about two and then goes to 5 I have tested that wire all the way to the control module and there's no resistance why would it do that?

Is there a black wire with a blue tracer on that connector?
Unplug the map and leave it unplugged and try to start it.

Did you put a whole new distributor in or just the sensor? Whole new distributor will need the sync set for it to run.
Can your scanner do that?
