My car is doing the same thing I had the PCM rebuild with the skreemalator delete it started one time then now it does not do anything. Will not start the fan spins fast then to a slow speed the spoiler came up I checked all fuses are ok I checked the rcm Not sure what can be the problem I love my Crossfire but wonder if I should get rid of it its becoming a money pit. I love Little RED. I will continue to tinker with it now that it is to cold and I do not have a warm place to work on it, it may have to wait until Spring. I have a trickle charger on the battery and it has a full charge and the battery is only 6 months old. I wish I could afford to gut the car and make it all electric LOLOLOL..
