Need help, starts and dies, no refire I'm a little new to the ls. Put a 2000 5.3 in a 1997 S10. I reworked my own harness, had the pcm flashed for my specs, vats are removed yet this thing will only run for 8-10 seconds and then won't refire. Have to wait at least 5-15 before it will restart again. Fuel system has new pump 55 psi at the rail, its got spark obviously, yet this Sob will not stay running. Help.
