Check the white/green wire in the big bulkhead plug on the passenger side. That plug can corrode internally and cause weirdness.
If you unbolt the distributor and turn it can you hear the injectors pulse and can you see a spark? If yes to spark it means your hall effect is good and your ICU is working. If no injector pulse then check the injector circuit for grounds and the white/green wire I mentioned earlier. It should have 12v on it with the key in the run position.
The injector pulse is triggered by the hall effect that tells the ECU the engine is turning so fire injectors and run pumps.
