More info than "it doesn't start" would be extremely helpful.

Have you replaced your CPS? Do you notice a pattern with the car being harder to start/restart when it's hot? When the car runs, does it run well?

https://www.crossfireforum.org/forum...-no-start.html is definitely the first place I'd look, followed by the CAS if you haven't replaced it yet.

Won't be more than a few bucks to check both of these - the CPS is sub-$100, and RCM is free if you know how to solder at all. Both are very easy - the CPS is just a simple one-bolt remove and re-install and the RCM just slides out.
