I can't specifically comment on the Crossfire since I have only owned it since May, but other FI cars I have owned over the years have known to flood. Can't say why but it happens.

Anytime you suspect a flooded engine, hold the gas pedal down to the floor before you turn the key on. By holding down the pedal, you are telling the ECU to 'clear flood' . With that, no injectors will spray and you are allowing maximum air into the cylinders with the throttle body wide open.

If it still fails to start, do not let off the pedal, but turn the key off for a minute or two. That will allow some fuel to evaporate and also let the starter cool down. Attempt again to start it without letting the pedal up. From my expierence, the second attempt will general start the car if it was truely flooded.
