Hello,
I have a 04 fire with 28k miles. Ive had it for a few months and I am having some issues. So far I have had to replace the window mirror switch, key ignition and transmission sensor o-ring.

Right now I am having starting issues. The car wont start for the most part. When I go to crank it all the dash lights come on nothing happens. I do not hear the fan. Everything is quiet. However I have tried a few times and sometimes I can get it started. Also the spoiler is up and flashes red light when all lights come on.

It has a check engine light on. P0600A - Serial Communication Link.

If I start it I can drive it....unless all the dash lights come on. Then it will NOT shift out of park. If for some reason I start it and put it in drive and the dash lights come on I can only drive it in 1st Gear.

Is this the RCM?

It was diagnosed at a Chrysler dealer which said it needs a relay and possibly shifter linkage but they dont have the parts. They put on paper 5099007-AA Relay Non 08052328 Sop Bo Pos Local $85 More...is this a fuel relay??
