2004 chrysler crossfire will not start

Bad battery, bad starter, bad ignition switch

New battery, starter and switch

The fob's battery may be dead. If in doubt, go to a good locksmith that deals in car keys. It doesn't cost much to change that battery. The other answers are also correct.

How about a few more symptoms. Does it crank? Does it fire up and then shut off? When you turn the key on but not to the starting position can you hear the fuel pump and the fan?

Change the battery for the fob. No crank, does not fire up, yes fan and pump is running.. ?????

Sounds like what we call the mystery no start issue. There are three solder points on the RCM that need to be resoldered. An easy fix. http://www.crossfireforum.org/forum/tsbs-how-articles/38483-how-repair-relay-control-module-rcm-mystery-no-start.html Join us as well on the Chrysler Crossfire Owners Group on FaceBook.

The three points was solder and still no start... What to do now???

Same issue here with an 07 Crossfire, I changed both crank and cam sensor, soldered the three points, changed the battery and the car started. :-O however, a little later it started starting intermittently so I bought a new relay box, same issue still. :-|
