WHAT IS MAKING MY VAN SHUT OFF RIGHT AFTER IT STARTS?

2000 GMC Savana

I have replaced to fuel pump, regulator, filter, and tested the pressure at cranking it's 60-65 pounds. It will run fine if I'm spraying carb starter in. Spark is great and I tested all the fuses and everything there is fine. No leaks in vacuum lines. Please tell me what I'm missing.

Is your security light on or flashing?

The security light comes on when you turn the key and then goes out
