#739 of 1240 2001 Jeep Grand Cherokee won't turn over....
Aug 08, 2010 (11:09 am)
I have a 2001 Jeep Grand Cherokee Laredo 4.0, 6 cyl that won't turn over. My wife stopped and filled it up at the gas station and when she went to leave, it wouldn't turn over. We jumped it at the gas station and it started fine and we were able to get it home. Took the battery in and the battery was fine. We changed out the starter and have checked all battery connections but still no luck. Just a clicking sound when engaging the key to start it. We have power inside. Any ideas??

Since it started when it is jumped i would rule out anything sensor related in your car, if it had been your starter, jumping would not have helped. I know you said you checked battery, but it really sounds like a bad battery. You said you took the battery some place. Out of car you took it? I don't trust a check like that on the counter of a parts store, it checks voltage but not cranking amps.Instead of wasting money on starter, battery is a better thing to change out. Jump your jeep, start it, drive to good parts store like autozone, they will check cranking amps as you try to start it. They also install the battery for free. If the vehicle started with a jump you can assume all circuits are good except for battery- if that battery is close to 3 years old, replace it, but i would want it tested still in the vehicle, that way they can first while it's running check voltage to make sure all cells are good, they can also see if alternator is charging battery, if it is but voltage is low(below 13.5 vdc) its the battery, test can also see if alternator is charging. That is the best way, instead of throwing parts at it. If battery is several years old, its highly suspect, enough volts to turn lights on dash on but bo cranking amps, but jump it and take it somewhere that tests in the vehicle, not with battery sitting on counter in store. Where did you take the battery to test?

I had the problem back in November. AAA came and jumped my car, said the battery was fine. It did it again and I also had power on the inside of the car. Took it to the Mobile gas station at the corner and they tested the battery again and said it was fine as well as all of the connections. As soon as the mechanic was getting ready to close the hood of my car the battery gave off some sort of fume and the mechanic said, "okay... this battery is no good". I forgot what he said was wrong with the battery but the fumes smelled like rotten egg. I purchased a new battery and they put it in right there. I never had the problem again. Again, the bested tested fine two times being hooked up to the machine but was no good. The old no good battery tested over 14.

I had this problem with my 99 Grand Cherokee Laredo. The mechanics said my battery was fine so I changed out the battery terminal connections (old) and I have not had that problem since...

That seems to have worked! Thanks for your help!
#744 of 1240 Another Jeep grand cherokee with starting problems
Aug 12, 2010 (6:50 pm)
I have a 00 Jeep Grand Cherokee with the 4.7L V8. I went to start it couple weeks ago in the morning and it cranks but would not turn over. Used other car came home from work and the jeep starts right up. Next morning same story. Everyone I knew said fuel pump going bad. So changed out fuel pump and filter/pressure regulator. Starts up no problem. Next morning same ol issue NOT STARTING!!! I hear fuel pump prime it fires up. No pump priming no starting. The weird part is the smaller fan by radiator will whine and vibrate. This happens every time the fuel pump does not prime up. WTF someone please help. When it does crank over and I drive around it wants to stall when I stop as well. I have read hundreds of posts and not one with this issue. I do not want to make another costly mistake replacing things that work. I did check fuel pressure when running and it was 54 psi. PLEASE PLEASE give me some direction

I am new to this site and am having a bit of a problem. I have a 96' jeep grand cherokee limited. The other day i drove it about 100 miles with no problems at all then when i went to drive it home it wouldnt start it just clicked. At first i thought maybe my battery so the first thing i grabbed were my cables and then i realized that my lights were on so i thought maybe my starter was starting to go so after tapping on it and still not starting my dad said lets try giving it a jump. So we jumped it let it run for a bit and then he took his cables off and i went to get the kids...it shut off. So we tried again and it did the same thing so we loaded up the jeep and jumped it i stayed on the gas. everytime i let my RPMs drop below 1 1/2 it ould start to sputter like it was gonna die out (after navigating the back roads in deer county..no easy feet without slowing too much) we finally got to the highway but everytime i slowed down it would go to shut off. I noticed that every once in awhile the the check engine light would come on but only hen my little battery icon/gage on the dash would go up to full charge ( i guess thats what it means)and when it would go back to the middle (7) the check engine light ould go off. As soon as i pulled into my house it shut off before i had it in park. Unfortunately i am the only one in my family with even the tinest bit of auto knowledge and it is pretty limited...sorry for the long saga here but i wanted to make sure i told you as much as i could. i guess after all that my main question would be...is it the alternator? I just need something to go off of. I am going to pick up a used alternator this eveining just to start the process of elimination so if anyone has any other thoughts please let me know! Thank you to all of you who read this "book' that I wrote and to anyone who is able to help me out!

probably your battery........ take it to autozone for a free check..... your alternator is trying to charge the battery and run the car.... if the battery will not hold a charge the alternator cannot run the car by it self unless you keep the idle up real high.
could be a bad coonection at the battery..... clean the terminals ........... but my bet is the battery..... it has enough to run the lights but not enough to start the car. so it is prbably not holding a charge.....

I have the exact same problem with my 97 Jeep GC. I've replace the crank shaft sensor, distributor & cap, wires, ignition coil, catalytic converter (2) and today a new ECM. It runs a lot better today but it is still idling real low with the AC on and I'm afraid it will stall.
I want to share this with you. The ECM is the computer on the passenger side under the hood directly behind the radiator overflow tank. Before I got the new ECM I could push and pull or even just tap the computer and the jeep would die. So we decided to install a new one. So far in 20 minutes of driving (you know that's not enough to say for sure) it has not stalled. The ECM was $200 at advanced auto parts.
I'll update later.
#748 of 1240 Grand Cherokee Laredo Stalled and Won't Restart
Aug 14, 2010 (4:38 pm)
My son was driving his 1999 Grand Cherokee Laredo home this morning when at 45 miles an hour it sudden lost power and quit. It will not restart. We have checked the fuel pump, plugs, and gas lines. When you try to start it the engine will not turn over even though it is trying to. Prior to this happening it would quit here and there when you first started it and took your foot off the gas. The only other problem that we have had was the battery draining if you left it parked for a few days. We have yet to get that figuered out. No one can find anything draining the battery. My major concern is getting it started and it not quitting on my son again. Please help. We are currently looking at the coil packs. We would appreciate any suggestions.
