1999 K1500 starts but stalls right away

I bought this truck not running, knowing it needed a fuel pump and a new intake gasket. I replaced both and have everything put back together. The truck will start, but stalls out right away. It will restart, but continues to stall right away. The fuel pump I used was an airtek, and it required me to replace the wiring harness at the pump. I think I did that right since it starts (so I have fuel pressure when it starts). My guess is that the fuel pump is shutting off as soon as the truck starts, but not sure what is causing it. Could this be the fuel pressure regulator, faulty pump, crank sensor, etc? I would appreciate any help.

Thanks

sounds like a problem in the passlock system
Turn the key on and watch the security light....does it flash? if so, leave the key in the on position for 10mins (or until the light stops flashing), turn the key off, then start the vehicle
