My 94 300zx is running on 5 cylinders. I already checked the compression, which was good, replaced spark plugs, put a known working coil pack in for that cylinder, and spliced in a new plug to my injector. Leaving the only possible explanation to be my injector.
But then I used a noid light to my injector and it isn't pulsing, although I tested the wires and they are for sure getting power. So idk what to do? Was going to replace injector but now that I know that it isn't properly pulsing I'm not sure?

The computer might not be grounding that particular cylinder

Meaning the connection at the ecu? The main grounds on the harness seem snug, and nothing else seems to be acting funny.
