It is the 2004 automatic coupe crossfire. About year ago I had the no start problem which ended up being the RCM. After doing some soldering the no start problem went away and the car has run flawless until a month ago. Went to start the car and all the dash board lights came on along with the fin in the back going all the way up, but it would not start. I decided to go ahead and resolder the RCM and replace the battery none of which fixed the problem. Strange thing is if I try at it long enough the car will start and run fine until you turn it off then it goes back to not starting.

I also noticed when I could get it started the fin would never go down nor would the light stop flashing. Gave up on it after a few weeks and had it delivered to a dealership to have it look at. I was told today that the PCM will need to be replaced which is little over two thousands dollars. Before I give them the go ahead I like to hear if anyone else has come across a similar issue. I read the forum but so far their fixes hasn't worked for my car.
