How to Repair Relay Control Module (RCM) - (Mystery no Start)
I assume that you are aware that the cargo divider in the trunk must be in the position where you have little trunk space left before you can put the top down ?
This divider has a rod at the top that snaps into sockets on the left and right side.
On the drivers side of this socket there is a switch that tells the top control module that the divider is in the correct position.
This switch is kinda hard to see. There is a plastic slider that actuates the switch when you have released the top from the windshield frame.
This one is a bit of a PITA : it is INSIDE the trunk latch assembly. You would have to remove the plastic cover in the trunk lid, then using torx and 10mm wrenches, remove the latch assembly to inspect / meter this switch.

My 2005 xfire has the dreaded "no start" problem (no crank, burt all electronics work just fine). Usually happens when I park the car with a hot engine and then attempt to re-start shortly after parking. Once this happens, and if I let it sit for 20-30 minutes the car will start with no problem.
Are you still providing the exchange service? Thanks,

Still fixin' them.
Send your RCM and $25 (PayPal to (tighed1 at Hotmail.com) or cash is cool) to:
DJ TIGHE

I'll inspect, redo bad solder joints, perform the Me So Horny mod (horn works w/o key) and replace the Air Pump relay (and the Fuel Pump relay if needed). I will then test your RCM in one of my cars. Then I will mail back the RCM to you via USPS Priority Mail (2-3 day). In most cases I get the RCM back in the mail the day after I receive it so yer looking at about a week total. If you want the package insured please include an additional $6. FYI, In the couple/few years that I have been doing this only one was lost in the mail.
Please email your address to me also.

How are the pins in the connectors on your car holding up with all the swaps?
I should be able to do this...LOL! I just picked up a soldering & solder iron at Walmart on my lunch. Will drive to wife's work straight from work to get the most sunlight. I do have a question... after I open up box and unplug all wires... is RCM board just sitting in there lose or is it connected to something else I need to disconnect? I'm assuming one important point is to not have solder melt onto the connection next to it. If by some slim chance this doesn't resolve my car not starting problem....where do you suggest I look next. Thanks in advance for all the info on this site and any future suggestions and help.
I had to put anti-seize compound on the connectors. Was getting WAY heard to remove them. No other problems.

The RCM removes very easy and is just clipped in place.
If you have never soldered before google it looking for video results. Use only rosin core solder. Heat the board till the solder melts on the board while feeding new solder to the board not the iron.

Depends on your no start symptoms. It may not be the RCM.

Had no idea how long it's been since I was on this list last! My 05 Roadster has seen too little use, but has been flawless until tonight. Wife and I drove it to Mammoth Cave a couple of weeks ago, and it did fine. Tonight I decided to check something in the garage, and startled a rat! I'm in a very rural area, so this has come in from soybeans or pasture. Unfortunately, it has decided the Crossfire is a great car.
I wanted to get the car out and make it inhospitable for the rat, but got no start. My first fear was that the rat has chewed something at some completely inaccessible point, and I really do have a great piece of garage art now. But, symptoms match this thread, and I get no error messages. The central locking system works, so wiring and vacuum lines seem to be intact. I cannot find any damaged wires under the hood. I'll try resoldering these joints, but would appreciate any other suggestions, in case this repair does not help.
I've read in the past that too many attempts to start the car will disable it. Any truth to that? Can I avoid/undo it if I've already caused that problem as well? Found nothing yet in the FSM.
Thanks for any help.

Hey Michael
Oh no. If you havent changed your battery yet it also maybe a low battery .
I know it sounds funny but it just happened to me this year . These little babies are
Prone to not start even if the battery is a little weak. i have also read that here on
These wonderful forums!!!!! My 2005 roadster has been a great car only with a few
Issues low battery being one of them.... All lights will come on everything just wont
Crank if battery is low.

Maybe searching on SKREEM will give more details for that issue.
Seems the RCM, SKREEM and CPS symptoms overlap slightly and become confusing over the web when discussed or described.
This happened to me twice once at work and luckily the last time in my driveway. I took out thE RCM and 2 out of 3 of the joints I found cracked solder joints, heated them up let them puddle nicely put back in. Car starts right away. Thanks

At 71 my memory isn't what it used to be. I swapped my spare RCM with a forum member ( this is where my memory fails me ) at CAA6,
and upon returning home I took a look with a magnifier and all 3 joints where bad.
Re-soldered, tested OK, I now have 2 spares again.
( 1 spare is not enough, 1 for me, 1 for other members in need )

I put it in the car, make sure the car starts OK, the horns blow, and that the aux blower runs ( and shuts off ) on cold start.
( also no CEL light or codes )

Bill,
Thanks! I'll pull the voltmeter out this morning. The battery was new when I bought the car about five years ago. I have had it turn over slowly, but it did fine on the trip to KY two weeks ago. From what I could understand in the FSM, it can have enough fire for everything but start, but will not attempt to start if the voltage is too low to satisfy one of the control modules. That does match my car, what you describe, and also the bad board. I'll be checking both.
KDW,
Yep, the SKREEM no start. It had been a while, but I didn't see the part about not sensing the correct FOB (key fob?). I have been afraid of disabling my car with a minor mistake, apparently for no reason. A little knowledge.... Thanks for answering that.
Ala_xfire,
Where are you in the state? I'm in the extreme NE corner of Mississippi, Corinth, and rarely encounter Crossfire folks. I remember discussion of a northern Alabama Xfire meet when I was new at this, but it didn't make.
I appreciate the help, AND the great go-by, DJ. Will report back. Anybody want pics of the rat? .-)

hey Michael
did you ever find your problem?
Inquiring minds would love to know your outcome
So others can compare issues.
Hope it was an easy fix!
