Guess what. My Camaro devoloped a no start condition again. The other day I cold started my car and let it idle for a couple minutes then it suddenly just died as if I turned off the key. I was busy that night so I didn't check anything out. The next day I went to try and start it and after cranking for 5-6 seconds then it started to spit and sputter and finally fired up. It idled an revved just fine. Stupid me I didn't actually drive it as I didn't have anywhere to go. The. Come Sunday I went to start it and after idling for a couple minutes it just shut off and wouldn't start back up. Only cranked. Checked fuel pressure and I have have 0psi at the rail. I checked voltage at th fuel pump relay connector and there was 12v. Checked voltage at the body connector by the rear end and there is 0v with key on or cranking. To my knowledge there's nothing between the two is there? I'm kind of stumped here.

 

On which wire(s)

Does the relay turn on as it is supposed to ?
Did you check for power out if the relay?

Bit obvious , but have you checked the fuel pump fuse that supplies the pump power?
