Short of checking spark and power/ground to the injectors, I am leaning towards stuck injectors.

Anybody know how VATS works on the newer trucks? My only experience with it is the older versions with the resistor chip in the ignition key.
There is nothing like that on the key to my 03 Tahoe. Maybe it is buried inside the key out of sight.
The older system I was able to physically bypass by jumping a pair of wires under the dash. I yanked the computer and 305 TBI motor out of my 91 RS and dropped in a brutal 408 small block that no longer used any computer controls. It wouldn't start even though it still had the correct resistor chip in the ignition. Turns out there is a mechanics bypass harness out there so I was able to use that info and figured out what needed jumpered to get it to start with no ECM in place.
Maybe there are a pair of wires you can connect or a single wire you can supply power to that will tell the PCM that the VATS module is sensing the correct information to allow the engine to start.
