"Won't start"is an electrical problem. In numerous places on this forum, we have published the DIY technique to determine if it is the RCM. RCMs are inexpensive ($150 or so) and can be changed without tools by ANYONE.

A bad RCM causing a no start is probalby the #1 most common issue with our cars.

Get in the car.
Turn key to "START", if the starter does not engage, release key to "ON" and wait. If the engine fan is running fast after 30-40 seconds, your RCM is bad. Getting it fixed by DJ in Arizona or ordering a new RCM will get your car running.

If the starter engages, but the engine won't start, we have a few more tests to do before we know what direction to go.
