ENGINE WIL NOT RUN MORE THAN 3-4 SECS.

1999 GMC Van

Engine Performance problem
1999 GMC Van V8 Two Wheel Drive Automatic 140080 miles

I jump started a neighbor, it backsurged my system. I have a new battery, starter, rebuilt ignition system, remanufactured ECM, new ckp sensor, new fuel pump and preasure regulator. Fuel filter is clear. All fuses checked. I am not getting any dtc info from van. Is there something I've missed, or what do I do now?
