Ok so u have continuity between the power wire and ground. Im assuming you have also checked for voltage on this wire? ;) someone has probably inadvertently used this wire for something its not intended for or the alarm has it grounded. Either way just bypass it with a similar gauge wire and see if it fires up. Shotgun diagnosis I know but since you dont really know the state of the engine other than what you were told Id get it running then go back and spend time tracing the affected wiring.
If it don't fit force it, if it don't force fit f&%@ it!

yes had voltage I'm gonna try it I'll get bk to you
What if there's no 2 sec prime from gray wire
Then you don't have power to fuel pump from fuel pump relay.
But if your turning key on and off? Sometimes it will not prime until off for awhile, all ECM/PCM have different timers but 30 seconds should cover them all.
Does your fuel pump relay have an extra Red wire hanging from it with a plug on the end? If so you can run 12 volt Batt power to it to keep fuel pump on while testing.

k so trying to figure out if I had a short somewhere I check the wires. Under dash while doing this the black brain security box light flashed on then off then stayed on then just did this often so I continue feeling There is a short found a. Nic by accident touched w knife n it turns the car over like the starter over k so disconnect batt taped the red ignition wire I'm assuming n hook up batt n n ow no turn I over I even tested starter solenoid w jumper it's good I'm just lost. Now
a 1991 camaro rs didn't come from the factory with a black security box with a light.
you likely have an aftermarket alarm system.
maybe some idiot wired up a fuel pump disable with it.
i'd get that aftermarket alarm out of there, every single car i've ever owned that has one has been a huge source of problems.
K I have no pulse to the injectors what could I do?
Just looked up a 91 F car and it does have VATS enabled... so earlier you said it's not a VATS issue and you have pulse? Now no pulse with Noid light...
Is your key in good shape? Does it have the resistors in it? Did you recently get new keys? Is the key switch worn/loose?
Do you have spark at spark plugs? Even if you do it could still be a faulty EST module or wiring issue at EST in distrbutor.
I'm open to other ideas as well, but these are top 2 for no pulse injectors... could also be a faulty ECM. Are there any error codes set?
