2012 Jeep Grand Cherokee won't start

Asked by Apr 02, 2017 at 09:27 PM about the 2012 Jeep Grand Cherokee

Question type: Maintenance & Repair

The Jeep won't start intermittently.  The battery and starter have been
checked by the dealer and they can't figure out why it won't start.  When the
Jeep decides not to start it displays a check engine light.  But when the
computer is checked there aren't any fault codes

Must be loose connection somewhere or bad ground to frame.

I have a honda with the same problem and you have to test these things when they happen . I found it was a weak spark . If I wait 30 minutes it will start right up and go anywhere or you can break out the tools and have at it . You may have ignition relays , exciters , amplifiers and what not ! Intermediate problems are the worst . Let us know what happens .
