Exclamation Intermittent Start Issues

With the aid of this forum, I have been chasing an intermittent start issue on my 2008 Crossfire for a while now.

The problem is:
  • If I insert the key straight in and start the engine, it will start and die almost 100% of the time.
  • If I give the car a little kick while trying to start, it will start up just fine.
  • If I leave the key in for about 10-20 seconds, the engine will start about 90% of the time.
  • After 2-3 starting attempts, the car will no longer crank for a variable amount of time. The dash will light up just fine, though.
  • Once the car is on, the idle is perfect and runs / drives; it has never stalled on me.
What I have tried to fix it:
  • New Fuel Pump / Filter (all high-end OEM from rockauto)
  • Sparkplugs
  • Resoldered RCM and checked relays (the contacts look shiny, and no soldering issues were found, but I resoldered all of the pads)
  • Bosch Crank Position Sensor (I also have a cam position sensor on the way)
  • Mass airflow sensor
  • New AGM Battery
I have had the car for over a year now, and this issue has gotten progressively worse over time. With some of the repairs making a difference (could be a placebo effect), but a few weeks later, coming back.

My next ideas are:
  • New CAM position sensor
  • Clean the throttle body.
  • Check fuel pressure
  • Check the starter motor.
  • Check the clutch position switch.
  • SKREEM (I don't believe it is. Giving it gas starts the car just fine.)

Please let me know if I am missing something obvious!

Also, if anyone has a source for the 07/08 SRS module, that would be greatly appreciated!
