Exclamation Car cut itself off wont start now

So I finished up my wire tuck started the car to let it idle. It was idling fine for about a minute then cut itself off now it wont start again.

I hear the click when I turn the key so I assume this is either the fuel pump or pcm cutting on. Security light stays on while cranking but I have never paid enough attention to know if it always does this.

The needles are jumping after I stop cranking. Anyone have any ideas? Car was running fine. Checked my relocated grounds and made sure they are clean and they are.

I would check all my fuses first, that's easy enough to do. Try to use test light you wouldn't believe the number of people that think a fuse is good by looking at it and it is not completing circuit (blown).

If I released the fuel pressure from the rail and it barley dribbled out, would that mean bad fuel pump?

Fuel pump is not priming. Jumped the 12volt source and it primed and shut off like it should. However still no start. Not getting anything from the green PCM wire when the key is turned to on (also getting 6volts for the other power), does that mean either the crank sensor has failed or the PCM is not grounded properly?

Does it turn over and just not fire? If so I would suspect crank sensor wiring has come into contact with headers or exhaust and burned. If it doesn't even turn over there is another problem for sure.
