Re: GT500 no-start issues.
Yes. Fuses for the BAP are good and I checked for any exposed wiring that might have been shorting anything out back there. I'll be doing voltage checks for the BAP and checking the FPDM tomorrow.

Re: GT500 no-start issues.
Car is running, not sure what did the trick but I did quite a bit this morning before attempting to start it ( I know, I know, I should have ruled shit out but I was in a groove =/ ).
1) Checked all plug gaps / plugs for damage.
2) Changed out fuel pump related fuses, they all checked out good but I did it for good measure.
3) Checked BAP voltage/wiring for anything that may be exposed.
4) Swapped out the fuel pump / IC pump relays.
5) Reloaded my tune.
I'm sure I'm forgetting some things, has been idling in my driveway for 5-10 minutes now, going to let it go a bit longer before I try and take it anywhere.

Re: GT500 no-start issues.
Reloading the tune may have wiped out any short and long term trims that might have caused the problem. Might just be running too rich with the learned trims and the extra cold idle enrichment with the cooler weather. Does it have hot-start problems also?

Negative on the hot start issues.

Re: GT500 no-start issues.
If it happens again, do the following:
1.) Turn ignition into run position, BUT DON'T CRANK. Expose the shrader valve on the fuel rail and press it to see if there's fuel pressure in the rail. Clean up any fuel that may have spilled out. If there is spark, proceed to 2 otherwise you're having a failure in your pumps.
2.) Take an extra spark plug and install it on one of the coils; Put against the engine or something grounded, get someone to crank, and see if its sparking. If its not firing at all, its something with your ignition that's preventing EVERYTHING from firing. Notably, probably your crank or cam position sensor.

Sounds like and anti theft or immobilizer issue toe shouldn't be a mechanical issue with that low mileage of drive time unless it's something dumb like a soft set connector or something
