How to Repair Relay Control Module (RCM) - (Mystery no Start)
Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
I read tighed1's post and it appears that I have a RCM problem. I replaced the battery and my car still will not crank. All of the electronic works. Does anyone know if tighed1 is still repairing these boards? I have a 2005 base model crossfire.
I think I can do this, but do not feel comfortable doing it. I an not sure what type of solder or soldering iron to use. Also, other than visually checking the solder joints, how can I tell which ones are bad? Should all the joints be resoldered while I have the board out?
Any help would be appreciated.

I redid all on my new spare one just to be safe. Only did the big 3 on my original as the others look good. (See post 746 for pics) I just used cheap $6 iron and solder from auto zone.

There are NO lids that need to be open, if you are referring to the little caps on top of the wires in all the connectors,
LEAVE THEM ALONE !

"pull by the wires" means to pull the assembly up out of the big plastic box by grabbing the whole assembly wires and all to get it free, then disconnect the connectors to free the RCM from the harness.
1) Open the Control Module container box.

2) Push any wires on top of the RCM aside to access the RCM.

3) Grab the RCM wire loom and gently lift the complete assembly out of its nesting hole, tilting the front side up first.

4) Pull the RCM assembly free of the box and other wire harnesses.

5) Disconnect the wire connectors from the RCM. (all are unique, order of disconnect not important)

NO, not the "wires" but the wire "connectors" are to be removed.

Haha, right. I still dont see it...they look like all the other little solder things to me, but someone is gonna do 'em up today and HOPEFULLY i can get this car to stay on long enough to drive it to a mechanic for the immobile top/spoiler issue!! i just had to fix it so ot could be fixed. Makes sense right?

I got my PCM back from tighed1 Friday and installed it today. It took about 5 minutes. I am still having the same problem. The car started up and shut off in about 1 second. It did this about 3 times. After about 24 hours I will be able to start up and it will again shut off.
Now that I know my PCM is not the problem, my starter is good and I have a new battery, what is the next step in the elimination process to determine the cause of the problem?
If anybody needs their PCM resoldered, tighed1 is the guy. I shipped mine from Florida on Sunday and got
it back on Friday.
tighed1 keep up the good work.

Replace the CPS ( Crankshaft Position Sensor ) with a Bosch one,
if that doesn't resolve the issue, then next step is to borrow a fuel pressure gauge from Advance or Autozone and ensure you have 50-60 lbs of pressure at startup.
The test point is at the end of the fuel rail at the passenger side front of the engine.
Possible problems : fuel pump, fuel filter.
