Re: Crossfire cut out - engine won't start! Help please!
Sure, no problem.
The PCM, in the box where the RCM is (right next to the RCM), has 5 connectors. Connector 1 is the connector closest to the firewall. You want connector 4. If you pull the connector out and look at the bottom of it, it explains which pin is where (re-clip connector 4). You need pin 25, it's a violet wire. Cut it (far enough back to solder it back together later) and add a small section of wire for slack. Just twist them together for now. Then take the other end and touch it to the battery ground, your starter should then engage.
If it does engage, then strip and solder the violet wire back together.
