new rebuild won't stay running

[JSD69Vette]

well, I tracked down the power issue and it was one of the grounds at the back of pass side head. Now, I placed that ground on one of the head bolts that already had two grounds on it(easiest to get to). For reference, the factory calls for two grounds on each bolt. Now I have one ground one one, three on the other.

So, I set the genII, check all the plugs, set cam sensor with cam tool, all ok. Fuel pressure ok, 44#. TPS @ .42 and the IAC reads 150, both with the ingintion in the on position. Plug wires on correct cylinder. Injectors and injector plugs on correct cylinders. Go to start and it runs for a couple of seconds and dies. Tried this several time and same thing. Recheck everything then tried again, dies.

Hope provided enough info.

Please help!

What about the Maf and EGR?

plugged in, do I need to set them? I did n't think I did due to using a GenII?

This is why I need help.

def. check these, unplug the MAF and see if it stays runnin and make sure egr is not stuck by pushin on the diaphram or that it is gettin vacuum when it shouldn't.

could a miss adjusted/set crank sensor cause this problem?

Mine did this after an engine install, turns out I forgot about the anti theft feature in my Commander chip.......
