Have you checked fuel pressure?

If the test light stays on during cranking you have a short to ground on the trigger wire somewhere. Could be the wire itself or the PCM. This is assuming you tested this correctly using a noid light and disconnected from the injector.

You don't have power to both wires. You are checking it with the injector still plugged into it.
If you keep using a test light instead of a noid light you will be replacing the computer if you haven't ruined it already.

Wanted to make sure all the injectors were good since ya have to take the air plemon apart to test injector wires and since there is no Signal it back to square one

Do you have spark at the end of the plug wire?

Put the top of the motor back together tonight,had the old ignition modual tested it was ok,replaced the crank sensor and the wire that goes from it to the ignition modual,tryed to start it again and once again no spark at the plug,node light didnt work but has power going to the injectors.Priced a rebuilt ECM and it would be cheaper to just scrap the car.LOL

It would require more sophisticated testing but it sounds like there is an issue with the crank sensor circuit somewhere.
