eliminating VATS
Have a 93 camaro with a 3.4 and it will run for a second then die.I just changed the fuel pump on my back in the garage and I think the vats is keeping it from running.I purchased the painless VATS module to eliminate it,but the module is for a lt1, and the picture for the computer diagram is different. Does any one know what wire coming out of the computer is for the the VATS. ANY HELP WOULD APPRECIATE!

VATS disengages your ignition, fuel system and starter. When VATS trips you get nothing, no starter click, nada. It wouldn't run for just a second, the starter wouldn't even engage.
Watch the "security" light. If it comes on for a second, then goes away, VATS is working. If it stays on, VATS is tripped.
Your problem might be the fuel pump relay under the hood almost directly in front of the driver on the firewall. Could also be the in-line fuel pump fuse. Sure sounds like a fuel delivery problem to me. Clogged fuel filter, clogged injectors etc would make that happen too.

The security light is constantly on all the time and the car has run with it on.The car will drive perfectly then will just die and not start.Give it a couple of hours and it will start right up again.So it does sound like the fuel pump relay is getting hot and just shutting down.Allowing it to cool down a few hours might be the relay. Will change the relay first to see if that changes the problem.Thanks for the advice.By the way the filter was changed with the fuel pump.

fuel pump relay is a nice cheap fix. Relays are notorious for that. Good thing its nice and simple. I'd go that route first. As for security light, thats some problem you got, glad mine didn't do that and it was just a broken keyswitch wire LOL.
