okay there is a bulletin on ignition switches for these but its an issue you would only identify with a scan tool.

This bulletin is being revised to modify the Correction Information. Please discard Corporate Bulletin Number 04-08-45-005C (Section 08 – Body and Accessories).
Some customers may comment that their vehicle will not start. This comment is referred to as “no crank, no start with complete power.”
Additional customer comments may be as follows:
- A clicking noise may be noticed when the key is first turned to the START position, but no noise is heard after the initial start attempt.
- The “Security” light may flash immediately after trying to start the car along with the message “Service Vehicle” in the Driver Information Center.
- The vehicle may not start for at least 10 minutes after the first attempt to start the vehicle. Diagnostic trouble codes (DTCs) B2960 and or B3033 may be set in history in the BCM.
When the key is rotated from RUN to START there is a voltage signal sent to the BCM that goes through the PASSLOCK resistor in the ignition switch. This voltage signal may have an early ignition switch bounce (when going from RUN to START) that the BCM interprets as a failure in the PASSLOCK system and disables the starting circuit.
Using the chart below, verify that the ignition switch has been replaced at least once using P/N 10392423. After replacement of the ignition switch or replacement and reprogramming of the BCM, perform the 30-Minute Learn Procedure found in Programming Theft Deterrent System Components.
Install scan tool.

I would still wait till you have an assistant to crank it so we can check the circuit and follow it back before trying to get it scanned unless you have access to a scanner.
