Fuel pump relay not powering up from PCM SolvedSolved

Chevrolet Camaro 1995 5.7 LT1 199999 miles
No start, no fuel pump or its relay power.
Could be security system issue or pcm
Key was missing. Chipped key was remade... hoping its programmed correctly.
Could be a pcm issue otherwise. Fuel pump relay wont power up.

Solved the issue of the pcm (computer) not triggering the fuel pump relay, so the relay will fwd the 12v power to the fuel pump. Upon inspection of the underhood wiring harness I found where the small dark green, wht striped wire was broken... but really, 3-4 inches of it was missing. Couldve been sabotage, or rodent chewed and took a piece of the wire.
Progress, tho the vehicle still isnt repaired. Now i must repair the fuel pump itself. It was done improperly... so i am doing rework and repairing the fuel sending unit simulateously. Fuel gauge on dash board also did not work. Gauge problem is common in these cars from what ive read... I would say its a problem in the fuel sending unit (in the tank) most likely. The tank itself is not easy to remove... rear differential and exhaust must be dropped, unless an access door is cut in the inner body of the car... above the fuel pump (Take All Precautions if youre cutting with a grinder, or will create any sparks)

I purchased the car as is would not crank seller advised me it probably needed the key fob programmed. Did that several times I went through every ground I can find I can crank the car over from the starter relay so not a starter or locked up.

Does the gauge lights go out when you turn the key to crank it?
