In the fuse relay center next to the battery there is a starter relay. Pull it and clean terminals and connectors in relay socket. Brake cleaner spray works well. Put some grease or WD-40 on the terminals and try. The loose connection could be at the relay and not the battery cables.

Our car keeps randomly shutting off. I very sure it is the ignition switch connector the wires coming out of the connector two of them I burnt up and really corroded. I think it is numbers 7 and 6 I am trying to figure out where the wires go so I can rewire them.

2 more maintenence items to try. Clean the EGR valve and make sure it function properly. Replace the fuel filter and run a tank or two with fuel injector cleaner.

Good luck and let us know. :)

I read another post about a jeep that described my situation to a T! But I need futher help. The post I am referring to is "recently my 97 jeep cherokee has started sputtering when fuel tank reaches 1/2 tank. Loss of power & acceleration as well as bucking. Any suggestions "

there was a reply of "Check the fuel pressure /charcoal canister purge solenoid."
I am a newlywed and dont have any $$$ for a mechanic. Any help futher explaining what the purge solenoid is and how to fix it.

Please help.

Start by checking the fuel pressure and comeback with the actual readings that's both vacuum at pressure regulator and w/o it-again I want readings not the thumb or eyeball method

My jeep grand cherokee loses power and dies at the stop. Then when I put in drive it hesitates with a jerk. The coolent sensor light blinks occasionally. I have been told it is the fuel pump. Any suggestions.

You need to check the fuel pressure with a gauge and see if you are actually losing pressure, it could be bad.

When I am driving down the road sometimes my Jeep just loses all power and shuts down on me. I have changed the battery and had the alternator tested 3 times and it was good all three times. Do you have any idea what may be causing these problems for me?

Have the pick up coil and the crankshaft sensor tested. Seems to be a common problem on these Jeeps.
