HELP!!!

I have a 96 jimmy that I need help with. I was driving down the road and it just quit on me. It will start if I pour gas in intake but won’t stay running. I have gas and crank and fuel pressure but injectors not opening. There’s no clogged and I’ve changed fuel filter, ECM, cam sensor and don’t know what to do. I was told there’s a ground wire for injectors but don’t know where or what color, and need to fix it before it gets impounded. Can you tell me where to check for ground wires for injectors??

 

Fused power goes to the injectors on a set of 6 pink wires and then each injector is grounded (ground side control) by the ECM as each injector needs to fire. Check power and then you use a noid light to check the ground pulses from the ECM. If your injectors are really not firing and its not the fuse (ECM/Ign fuse 10) then it might be the security system disabling the injectors. What is the security light in the dash doing?
