Okay, checked pressure, 45+ psi ,starts great, I can hear the pump prime up, runs great, no codes, idles fine for 15 mins, and instantly shuts down, like a relay trips, No sputter, nothing. dies. Shows no codes at all.
Doesn't restart at all. fuel pressure at 45 psi. Turns over fine. I know if I wait 20 mins. or so it will start up and the same results will follow.
ANY INPUT OR TROUBLESHOOTING HINTS WOULD BE GREATLY APPRECIATED! I have Twin 17 yr. old boys beating the hell out of thier mothers new cobalt! HELP!
