Just spent a mindless week trying to fix my 2004 Crossfire and as mentioned several times on this thread the culprit was the CPS. The only thing I would add to the symptoms would be that the car would start cold but when it reached normal running temp it would crank but not start. Plus, when changing out the CPS be sure to get a magnetized TORX E8 socket or you will risk having the bolt drop into the world of no recovery.....
