Dizzy Fuel injector

'92 SC 285000mi. comp 175 178 174 175 rings and valve job at 189000 because of burnt exhaust valve.

I have an issue with #1 injector control.

Much work has been done to come to this analysis.
New plugs indicated no fire on this cylinder ie: still shiny new no indication of combustion.

With engine running (missing on #1) I can cycle the injector with a pigtail and the engine will smooth out.
Engine off, spark plug removed, fuel rail pressured I can cycle the injector and hear pressure release and also gauge goes to zero.

Is there a way to test the wires to that injector?
Or, does anyone have an idea how to proceed?

REWARD EXCELLENCE!
