My parts car has been sitting. Went to start, turned over, no start. Have fuel pressure. Not ECU, not DIS. Check for spark and have none. What's next?

Check INJ1 Fuse.. see if it is good, has anything been done to the car since the last time it ran?

I didn't pull that particular fuse. I will check that tonight. No other changes. Car was started last fall.

A distinct possibility. I haven't found any evidence, but haven't ruled it out.

Also forgot to mention, no codes.

And if u find that fuse did blow, the question would then be Why?

Fuse is good.

Check the connecter of the crank position sensor on the right side of the engine or do an ohm test at the connector that goes to the DIS.

I was going to also suggest crank sensor. Without any signal, there?s no spark. Won?t set a code until ECM takes over running motor.

AND the wire itself.
Perhaps it was the daily special for the the hungry local rodents.
Keep us updated.
