*UPDATE* - I bought a butane soldering kit, 60 tin / 40 lead rosin, and triple refined butane. (I figured if I can't get this to work at least my kids could use for creme brulee, jewelry making, and wood burning!) Without knowing for sure that the RCM was the problem, I couldn't get myself to buy a new part. I resoldered the three joints plus a few others that looked like possible cold joints. Note I had zero soldering experience before this. I read about proper soldering... it should look like a Hershey's kiss... not a bubble and took care not to connect anything that shouldn't. I used my phone camera, well lit area, and yes my reading glasses to inspect all the joints.

Well I put back in the CF and still the same identical problem even with a fully charged battery. I ended up jump starting it and test drove it for 15 minutes, testing accessories just to make sure I didn't mess anything up with my soldering and it seemed fine. Parked it, but still didn't start up.

I went to sleep feeling pretty resigned and figured I'd buy a new RCM but then remembered this other thing I had tested before that didn't work, but maybe it would now since I resoldered the RCM. From a different thread in this forum ...



I had read one person needed to do this for a few hours so I let my CF sit overnight grounding the system to reset the computer and amazingly ...

IT STARTED!!!!

Twice ... and then I left it alone with more ideas of switching out the crankshaft and camshaft position sensors next since there was one incident the car died while driving on a hot day.

Thank you so much for this forum and all the info from those responding, step by step instructions, tips, and encouragement. Not only do I save money, but I can understand my car better too! Thanks again - myxfr
