Question about 2002 Jeep Grand Cherokee
Problems started some time ago and no one has been able to figure it out, including the jeep dealership, and my mechanic. sometimes jeep will not start. will get nothing when you hit key...no clicking no nothing. they if you keep trying it, it eventually starts. also all the guages will all of a sudden start doing funny things. the odometer will flash, the clock will flash, and all the idiot lights will come on? the speedometer will even go from 60 to 0 and back. will not lose power though. supposedly it is not registering anything on the computer at the dealership because the "check engine light" is not coming on (the one light that might help explain the problem. they have checked all the wiring? could it be battery cables? battery?
I had the same issue with my 2003. It turned out to be the battery however the battery was fairly new. Discovered the alternator was bad and not properly charging the battery. Had to replace both.

Though electrical problems are often very complex, your problem sounds very much like a faulty ground connection. I would check all grounds, beginning at the battery, engine, fenders and firewall&dash support. (metal rail that runs across the bottom of dash) On my personal vehicles, I add an additional continuous ground that "bonds" all of these items to each other and the battery as well. If grounding is not being completed inside a control module, the problem may persist though.
