The fuel pump is responsible for sending highly pressurized fuel to the fuel rails. The engine can die if the fuel pressure is not high enough to properly atomize the gasoline properly. This is the best place to start. You should hear a whining noise. If you hear nothing, that is a strong indication that the fuel pump is bad. If it is not as high as it should be you either have a bad fuel pump or fuel filter.
The fuel pump may be going out sporadically. Check the battery cables to ensure that they are free of debris and are bolted to the battery posts properly. Follow the black ground cable to whatever it is connected to. The alternator is responsible for charging the battery, and keeping your Cherokee running. If the alternator goes bad , the vehicle will run off of the power supply in the battery which is there mostly for starting the vehicle and as a backup reserve.

I thought it was bad gas so I added Sea Foam and it started right up. But, that after a few minutes it died again. I had it towed to a shop today and they said it was a crank sensor.
It was a lot less expensive than the fuel pump they kept insisting it was. I've had no problems since. Clay answered 6 years ago.
I have a Jeep Grand Cherokee and it stalled on the road several times while driving. It just turned off. However it is now running very rough when idling at stop lights and it just does not seem to have as much power. It has also made a poping sound under the hood. The longer I drive it in town the worse it gets. It runs great on the open road. What do you think it is?
GCL answered 6 years ago. I had the same problem with my Grand Cherokee Laredo, k miles it starting shutting off while running. I called the JEEP dealer and they said that they would not charge me for the diagnostic if it was something simple. Since the problem wasn't continuous they had to keep it over night until the problem occurred so they charged me Finally it did while connected to their computer and it was the Crank position sensor.
The dealer was going to charge me The dealer had them for I changed it a week ago and thank God its running like a champ. This was a very frustrating problem. Even though the dealer ended up charging me to check it I recommend you take it to the dealer to avoid guessing.
I found a garage near my house and they didn't charge me to run a diagnostic and it was the crank sensor as well! Don't pay all that money to have your crankshaft position sensor replaced.
You can do it yourself. Cherokeeee05 answered 6 years ago. I have a Jeep Grand Cherokee and it just shuts off and back on while Im driving, its now just starting up whenever the hell it wants, put the key in a click, then try it again and starts right back up. I found a recall for the ignition switch, but the part won't be made available until mid september. This is a Huge safety issue and they are just dragging their feet. Alh answered 6 years ago. Changed crank sensor wires and plugs still won't start Any help please????
Kyleepp24 answered 6 years ago. I have a jeep Cherokee sport 4wheel drive. I get up to 35mph and it cuts out spits and spudders and back fires. Iv changed fuel pump, fuel filter, alternator, spark plugs, crank sensors.
Iv taken throttle body off and cleaned it and cleaned all sensors as well. Iv done just about everything and still can't figure it out. Anybody have an idea on what it might be? Tired of fighting with it! Mary answered 5 years ago. My carb floater was stuck wide open pouring gas into carb. Did a rebuild and problem went away for a while. Your engine could be choking on gas. Then it only did it when it rained.
Changed distributor cap and it stopped being moisture sensitive. Still have trouble getting started. No not the starter. It feels like gas isn't getting up to the carb. Hectorr answered 5 years ago.

Dina answered 5 years ago. I am glad to see I am not the only one experiencing this problem. Thank you all for your advise. I was told it may be the crank sensor, I hope that's all it is, because stalling out at pm on a dark road with your 15 year old daughter on the curb of a major highway is not something I want to ever happen again.
I tried the two screws in the computer thing tonight. My poor ol jeep.. I changed, everything I changed everything but the logos on the side that said Jeep.. I changed everything.. Joshua answered 5 years ago. The cam sensor is cheap to buy and easy to replace. The crank sensor is not, make sure you dont buy the cheapest one you can get, because they are hard to change and you will have to change it right after install because they are junk.
I got my 3rd one from Summit Racing, it fixed the problem. Make sure you reset the computer after install, so it learns how to run with the new components. There is a procedure you can google if you dont want or have a scantool to reset it. Steve answered 5 years ago. It depends how it's dying, but if it's going say from rpm to zero all at once the cam sensor which is actually in the distributor and the coil should both be replaced as the first attempt.
I don't know why the cam sensor is so finicky, but in the old days we all knew about coils breaking. The high voltage coil is of very thin wiring and if there is a weak spot it can break. The coil may still work when it is cool but when it gets hot a gap may develop which prevents the electricity from doing it's thing. No electricity goes directly from the battery to the spark plugs. The electricity goes to a fairly resilient thick wired coil that generates a large magnetic field, and the fluctuations in this magnetic field create the high voltage in the other side of the coil.
If one of the wires in the coil breaks almost always high voltage side , strange things happen. I'm not sure why the cam sensor is so fragile, but a mechanic told me if you are replacing one replace them both. Might help but with cars being so electronic now there is so many things that can go wrong. My jeep, none of the buttons would work for power windows except the driver's side controls. I found a video online that showed how to take the switch apart and re-solder the circuit board and problem fixed.
I think it's quite possible many of the solder connections are prone to stress fractures like this switch was. So it means all modern cars are basically useless after 20 years even with good maintenance because of all the electronics.

I was going to change the pcm but dealer said it wasn't the issue. Yes, looks like I'm going get rid of ol' betsy may check out one the regulators and see what happens, the last heehaaa!
Replace the oxygen sensor closest to the exhaust manifold or unplug it and test drive to see if it runs better first. Had the same problem aftermarket O2 sensors only last a little while just by unplugging it make the truck run a million times better. Nikolaos answered 5 years ago.
Im thinking a sensor problem, any thoughts would be greatly appreciated, i live far away from a jeep dealership. Anyone reading this try to change the Crankshaft Position Sensor! I did so on my Jeep Grand Cherokee that kept shutting off while I was driving and now it runs great!! The Voo Doo fix works and so simple! About four years ago I had the engine stall problem just like all the previous descriptions. Both sides. Tie wrapped the connectors to the ECM and worked for four years without a problem.
Identical symptoms and getting worse by the day. So I thought I just needed to clean the connectors and replaced the tie wraps. Did NOT work!!! Works perfectly!!!!!. I recommend to do all of the above. Do not just put in parts until you have done the above! Alan answered 4 years ago. I had the exact same problem: the engine would just randomly turn off while driving or even sitting still. I replaced the crank sensor, but it didn't fix the problem.
I tried the "Voo Doo" fix and it worked perfectly. See Steve's picture above. I have had no problems at all since doing this crazy repair. Sergio answered 4 years ago. Hi everyone! These solutions seem very promising for my problem grand cherokee. But no one has mentioned all of my symptoms: -Engine turns off and on right back while driving, or completely dies if parked.
No problem to turn it on again. Only dashboard lights and gauges briefly die. ShortBus09 answered 4 years ago. Yourmechanic was featured in. Popular Jeep Jobs. Auto service in Your City.
