What is making my van shut off right after it starts?

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.

Do you
have the same problem?

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