So I bought a non-running Crossfire roadster that someone who loved crossfires was working on, but had passed away before he could complete the repair. When I got the car shipped to me his daughter told me she thought it was the SKREEM or the RCM and was including all the parts she saw. I went to look in the box where the RCM is, and there is a module missing in the middle. I've read on here that the PCM is expensive and must be coded to the VIN. Is that what I'm missing? If so, is there any way to get this somewhat cheaply?

 

Yes your PCM is missing. A PCM have to be coded to to your Skreem and have to be the right one for your Crossfire (manual/automatic) there are a few different part numbers for the PCM so it's not so easy to find out what part number is the right for your.
I have tested different part numbers in mine (automatic) and the car starts always but sometimes I have communication errors between other control units.
Please look if the skreem module is in the car, it is behind the speedometer, if not you need a complete new set skreem, keys, pcm.

 

Good news, I contacted the seller and she is sending me 2 PCMs that she found in the garage where the car had been stored. I'm guessing one is the original and the other is one he was trying to get to work or something....

Hopefully I can get this sorted out.

 

With the PCM's you can figure out what problem the Crossfire has. If it starts three times for 1-2 seconds and do than nothing you have the false PCM or a skreem problem.
