OK, had the RCM giving me the no start 10 days ago ( https://www.crossfireforum.org/forum...ire-today.html , POST 6618 ), with OBVIOUS solder cracks (Repaired, it worked for a couple days. Resoldered some questionable MICRO cracks, again it worked a couple times). Looked over a third time with absolute frustration getting PI$$ED at myself for not understanding why it was doing what it was doing (RCM NO START)!!!
FOUND IT, TOTALLY BY ACCIDENT! OK, maybe not by accident but it was QUITE a challenge since I knew it INVOLVED the RCM symptoms! The 5 wire connector (over the years) stressed the ring parts of the wired plug (inside the connector) and they broke off and separated causing an OPEN inside the plug (whenever a vibration occurred across any one or more of the THREE connectors!) I have tried almost 4 hours this morning sourcing those crimp-on connectors (needing two sizes) and cannot find them anywhere! I NEED THE 5 WIRE PIGTAIL with enough wire, to successfully fix my wiring. There is NO WAY I can repair those three 'tips' on the three that cracked/broke off!
I am ANNOYED MB/Fiat used those cheap brittle crimp-on parts and VERY HAPPY I finally found the problem. I then went and checked the rest of those RCM plug pins and am confident the rest are NOT stress cracked (using a headband loupe magnifier, in the hot and humid garage), sweating like a distance runner in the hot Arizona desert (no dig to Arizona, I probably lost about 5lbs total, which IS a good thing). NOTE plug @ pin # 4 in the two pictures, looks like that pin was overheating and slightly 'melting'? Suffice to say, 2 pictures attached! I want my baby fixed!!!!!

This was really great information.
Thanks for taking the pics and posting the issue along with a fix.
There is a XF write off here in Calgary. The owner has joined this forum (JNC852) and He's been selling off parts over the past few weeks. If you need the part, reach out to him, I can swing by, check it out. if good I could get it mailed off to you.

I've resolved to install a 12,000 BTU portable air conditioner in my garage VERY SOON. The only 'work' is drilling a hole in either the wall or the side-door to the outside to duct the hot 'condenser' air to.
Just as big a factor as working in the cool is getting rid of 99% of the bugs!!! (some will always make it past even a closed garage-door) EDIT: I just ordered one from Walmart.com for $315
Hi! Thanks for this post. I have been suffering symptoms of a faulty RCM for the past two years. I replaced the RCM once and it seemed to get better, but then the issues returned and I replaced the RCM a second time (thanks to the FCP Euro warranty). The problems persisted to the point of me thinking about selling the car, which I really did not want to do. I read this post and checked the electrical pin bushings. It turns out the connector B pins 1 and 2 where cracked. I got new ones from Pelican Parts and soldered them in today. So far the car has had no more issues! THANK YOU.
Now we have a recurring problem. How many miles on your car GHOST? You think it is an age thing, or a bad batch during production? Is your car keep inside a nice dry garage or outside under a carport ?? What's your take on the cause of these bad connectors. I guess we should all pull that connector and take a good look!
Hey, I'm having an issue with my car not cranking at times and the machinic told me it may be a computer problem...which scared the heck out of me. You fix sounds good but I am a female that has no idea when this stuff is...and I don't trust the dealership in the area and can't find a machanic to work on it. Any suggestions? Thanks!
Wdonovan Most common no crank problem is with the relay control module. I can refurbish your RCM to eliminate that as being your problem. Email me at tighed1@hotmail.com for the details.
