2004 Chrysler crossfire will not start

Hi. That does sound a bit strange. I’d like to no if you found the problem yet. I would suspect the rcm. The early reply mentioned humidity and temperature. Both possible if there are extreme differences from inside to outside. You don’t have a distributor on a crossfire as they are coil over plug. I could write here for an hour to try and cover all the possibilities but if I had more details maybe we could figure this out together. I own 5 crossfires. 1 base model and 4 srt’s. Guess you could say I like the cars. Trust me when I say I’ve have had my fair share of issues but all have been solved without much cost. Information / symptoms are key to the solution
