Default Start no run
Starts up but no run...

I have a 1956 Connect and cruise LS7, 4L65E, with American Auto Wire car wiring and GMPP for engine.

I have 12 volts direct and 12 volts pink from AAW wiring and HEI wire when the key is turnedon.

The motor will fire and die in 2-3 seconds

I have no idea whats going on
I have no codes on the read or logged on the Can Reader

Not sure your ECM has it, but it sounds like VATS (Vehicle Anti-Theft System) rearing its ugly head

Thanks for responding. I purchased a connect and cruise LS7 with 4L60E. I just fired it up lasted 4 sec shut down.
Do Connect and Cruise crate engines suffer from VATS?

I have a light on the fuse box (mil) light,
I have checked input on pink wire 12 volts ACC, and crank.
Starts and stops like the ignition stops, and the fuel is strong.
