Hi All,
Happy New Year. With the holidays, and the rain in California, I've only had a few hours to work on my car. Here's a quick update. I checked the RCM as suggested by tighed1, and only one of the relays was closed when I put the key to the on position. I replaced the RCM with a known good one from another crossfire - both relays were closed, and the spoiler now works. Still no crank. I stumbled onto a post about how to manually get the shifter out of park - there is an assess port near the drive symbol on the shift plate (never noticed it before), and using an awl, I was able depressed something in the hole to get the shifter out of park and put it into neutral. I tried starting it again, and for the briefest second, the starter tried to engage. Since I wasn't expecting it to work, I had only connected the negative battery cable loosely - at the time I thought it didn't start because of the loose battery cable. I tightened up the battery cable, but nothing happened - no crank. I also tried to manually start the car by putting the key to the on position, shifter in park or neutral and jumping the starter solenoid - the car cranked, put never even tried to start. I'm inferring from that brief initial crank that my wiring is okay, but something else is amiss. I think my next step is to check the brake switch and the transmission neutral safety switch. Looking at Rockauto, I've found what the brake switch looks like, but they don't sell a neutral safety switch - does that reside in the TCU or in the shift lever?
Thanks for any help in advance,
Sincerely
Jerry
