Jeep not running right!
what i do when i see cars that act like that is check fuel pressurse when the problem is acting up also check the spark to see if it is present at the time of the no start also when the check engine light comes on set up with a shop to check forr codes when the light comes on dont shut it off until the scanner can rread the codes. also that veh is equiped with a auto shut down relay system what is does is if a crank shatf sensor starts to go astray it can send the computer into shutdown mode also the o2 heaters can short out and that will send it into shut down mode also when it goes to shut down you will see it on a scan tool that the relay is shutting down also look at the grounds for the cruise control its usaully not the asd relay uaslly a system connected to it that shuts it down. hope this helps thunderboltz
