Question type: Maintenance & Repair

My 2002 Overland would at first stall and shut off while driving... or sometimes
when I drive it for a while, stop at a store or for gas, shut it off... it won't start up
again.  After about 45 minutes to an hour, it will start up as if nothing happened!  
Help!?  Jose Bx, NY.

Sounds like either a failing ignition control module or a dying fuel pump. Sometimes the ignition control module (ICM) will work fine until it gets hot. Then it'll break down and quit preventing the engine from starting. If you suspect the fuel pump, hit the bottom center of the gas tank a few times with a hammer when it won't start. If that gets you going it's definitely the fuel pump. Hope that helps! Jim

My GC did the same thing, they have problems with crank and cam sensors. I replaced both and problem went away. Note use genuine Jeep parts as they don’t like aftermarket sensors, I found that out the hard way.
