I have a 2005 Crossfire. Starting two and one half years ago the car would occasionally not start. When turning the ignition key the instrument panel lights would illuminate but the car would not have a signal to start. There was absolutely no noise from the engine compartment. I first thought the lack of starting was somehow heat related, as the failure to start seemed to occur on hot days and generally in the afternoon. The failure to start progressed over time to include the car shutting down while in operation. Now the car is undependable as it fails to start and will shutdown frequently while in operation. There is no common thread or pattern that can be discerned.
I have read the various posts about this car. I have visually examined the RCM. The module looks pristine. I believed I detected a hairline crack in one solder joint when examining it, thought it may have been wishful thinking. I re-soldered the joint. The car ran well for a few days and then one morning it failed to start. The car had been in the garage overnight. A few days later it started up with no issues.
I elected to replace the Crankcase Position Sensor (not a Bosch brand). Once replaced, I started the Crossfire and it started immediately. I decided to let the car run since the engine had not run for two weeks. I walked away from the car for about 15 minutes. When I returned it had quit running. All the instruments lights were illuminated. I immediately attempted to restart the car. The engine turned over well (normally) but would not start. I disconnected the battery thinking the computer needed to “reset” because of the new CPS. After 15 or so minutes I reconnected the battery. I attempted to restart the car. As before, the engine turned over well but would not start.
The Crossfire started the following day.
I would appreciate any suggestions anyone would care to offer.

 

"not a Bosch brand" - get a Bosche CPS.
RCM most likely still has an issue, all the symptoms point to that.
PM tighed1 and see if you can send it to him for a rebuild.

 

Also, you can't just "look" at the RCM - it really needs to be examined under magnification to see the flaws. Give it another look, or just re-flow all of the specified terminals to be safe.

And, +1 on using a Bosch CPS

 

yes sir as the others just mentioned, you didn't read enough. You can only see the flaws in the RCM under a magnifying glass. YOU MUST use a Bosch CPS. Others will fail almost immediately. No cutting corners on this one.

 

Did you ever have the error code(s) read?
They often tell you exactly whats wrong, other times not so much.
There is not much point in having this feature if it is not used.

 

welcome to the forum

 

My nickels on the CPS, although it should of indicated a fault code of some kind. Interesting !

 

CPS won't give a fault code usually. Neither will the RCM. They will give you the no start, or turn over and no start indicators though.

 

There is always the camshaft position sensor, this is a rare failure but it does happen. This part must be Bosch as other makes have not worked straight from the box. Get a Bosch CPS as well.
In fact buy two, one each for a spare.
It is possible that you have more than one problem.
