Default Ls1 won't stay running.

Not sure if I've put this in the right spot as this is my first post, admins feel free to move it if necessary. Basically my Dad and I have an ls1 that is firing right up but dies in 2 or 3 seconds. We have checked all grounds and power to ecm. All wires that are supposed to be hot or stay hot are in both run and start positions. We unplugged the MAF still same thing. Dad says the ecm had VATS tuned out so it shouldn't be that either. We are thinking it's a tuning issue but wanted to ask for other opinions.

Sounds like VATS has not been turned off.
