I'm having a problem with my 96 Grand Cherokee and I hope someone that has experienced this same problem can help. It seems like I have an intermittent loss of electrical power for a split second at no regular intervals. It will run fine for about a week then out of the blue it will just act like someone turned off the ignition for a split second, but it never just dies! Has anyone ever experienced anything like this before? I've already replaced the PCM and the Throttle Position Sensor and now I'm leaning toward the coil or ASD Relay. Need advice, please help.

 

Nobody had this problem or anything similiar before? Could it be tied to the factory security system? Does anyone no a way to disable it so I can see if stops this problem?

 

I had loss of power, but I found out that the negative cable was corroded and had bad contact. It would start every day for a week or sometimes 2 weeks and one day will have power loss. I was scratching my head over this.
I did develop a "bold spot".

 

i had the same problem i put new batter cable clamps on and cleaned the terminals and it never happened again..make sure u buy good clamps because i first put on cheap ones and they did the same thing buy the ones that are like 8 bucks each and they will last a while.

 

Thanks for responding guys, this thing is about to drive me nuts! So ricky are you saying that you had the same problem that I'm having or the the same problem trucker had. My Jeep never fails to start or never has a total loss of power when trying to start. It always does this while running, sometimes when it's in an idle and sometimes while running down the road. However it has never totally died or quit running, it could however be losing a ground somewhere somehow!!

 

check your groung on the left side of the battery on the fender

 

Thanks ricky, I'll check that ground on the fender and it still has the factory battery connectors so I believe I'll change those while I'm at it! I'll let you know if any of that helps! Anything else come to mind right off the top of your head?
