This car had this problem 2 yrs ago and the crank position sensor was replaced. 6 mo. Later it reappeared again and ignition module and crank sensor was replaced under warranty. Now it has happened again so this time I did the work and replaced the crank sensor ,ignition module, and the 2 coils. It still will not start...no fuel or spark. I will say that when it went bad it would not start for 3 days and then on the forth day it started . I pulled it in the garage and turned it off and the next day tried to restart and it was broken again. This is the way it was doing the first time. it would start and I would go somewhere only to have it not start later in the day. I believe the parts I installed to be of good quality so I don't know what to look for next. Is there anything else that could cause this?

I believe you are having the immobilizer problems with the alarm system,

This car does not have any kind of alarm.( I recently checked grounds going to different places and they were all good. What I need is a good wiring diagram but cannot find one for this model.)
