Shouldnt, I had mine out for late July, all of Aug and Half of Sep, fired it up right away.
I still think it's something sensor related (or possibly even tune, but I would say moreso sensor). It makes no sense as to why it would fire and then immediately shut off. If VATS is fubar, then your car won't even start. VATS prevents the car from starting, period. It doesn't let a hijacker put it in first and lurch-start it in gear for 5 miles.
i know everything is hooked up right and what not..my buddy just had a VATS problem on his duramax and said it would start and shut off immediatley...and also my brothers grand prix had a problem with his key and it would do the same exact thing so thats why i think it could be....do u guys still want a vid?
Check this post and see if it helps any. https://ls1tech.com/forums/wiring-stereo-electronics/225115-security-light-comes-wont-let-me-crank.html
that is a pretty interesting thread....i did ohm test my chip and got 3.01 ohms which is one of the values...but is this a common problem with the wires rubbing...

if its only running for a second or two, scanning it for codes with an autozone scanner isnt going to do much. my CPS, camshaft positioning sensor, for no reason bit the dust and was doing just that, starting up and then turning off.

I would take a deep breath if I were you, then immediately re-trace my steps. Check for the basics first; sensor connections, fuel pressure, vacuum leaks, etc. It's something that you either "forgot" to reconnect, installed wrong (being impatient, and in a hurry), or you tripped the VAT system...
Curious, did you disconnect the battery before you even started the process, or midway....?
