Use a noid lite, check for injector pulse. It is possible to have fuel and spark, but, without rpm signal, no injector pulse.

Engine cranking, can you see injector spray pattern, TBI? I've seen injector spray patterns that looked good to me,but, when I used a gage and check fuel pressure, the pressure was half of what it should have been.

I don't believe that sensor applies to distributor ignition.
