Same happened to me. No car mechanic could find the issue and it's amazing how everybody says "it's the fuel pump", it was so frustrating I was about to give up when finally a neighbor took it to some shop across town and they properly diagnosed the crank sensor and also did some modifications because the crank sensor would get lose, got it all snug and has been working fine since. I was so happy when they finally solved the problem.
The guy I took it too, he saw something on the scanner he hooked up to it. But it was a small shop. But the guy has been around for a long time. Just glad to have it running smooth again.
I had the same issue years ago with my Jeep Cherokee. I spent about $3,000 on 3 different shops and they couldn’t find anything. I ended up selling it and found out this same information 3 months after I sold it. I do love jeeps but that was the last time I ever bought another one. Some jeeps even have the plastic radiators that cause issues too. I needed up buying a new tacoma instead.
Since the ECU is mounted on the firewall the connections inside the computer get hairline fractures. Pull the 3 main cords off it pull it out bust it up. Remove the silicone waterproof and get your multi meter. Do continuity test
I'm having the same problem with my 2000 jeep grand cherokee laredo it runs for awhile then shuts off I have to wait about 20 minutes before it starts again I'm going to replace the crank shaft sensor today thanks for the information
Mine just died, I turned the key off and restarted it no problem. A few days later it died and could not get it started. Ended up being a large plug behind ECM coming loose! I replaced the crank senser before finding this problem!
Ive been having this issue for about week now with my 2004 JGC v6 it had shut off at stop light so I threw it in N and cranked back up kept goin and I notice it will kinda struggle to pick up speed if Im driving it I took it to mechanic and it stalled as I was pulling up to the shop to see if they could use scanner on it but my engine light isn’t on so nothing shows up and when the mechanic drove it he said it didn’t do anything with him so I left and right when I turned on my street it shut off
@@ctdope You are correct. It is a straight 6. I typically do the same thing. I just mean 6 Cyl but say V6. But you are right it is a straight 6. And that's the reason I hate to give up on this jeep. The motor is just awesome. The rest of the jeep is a rust bucket.
@homestead_diy I also have a 2004 GC, but its a 4.7 V8. I got it from PA, shipped to Florida. It has rust from up there sadly. So that means, it's days are numbered shorter than if it was in a western state. I love it, but I know, I won't be able to keep it 4ever. It has its issues also. The computer doesn't seem to like O2 sensors that aren't MOPAR, and MOPAR wants almost $800 to replace all 4. It's crazy how some parts are so expensive for an old vehicle.
@@ctdope The people I bought mine from had moved down from Illinois. So it was exposed to a lot of salt. The big rust spot I have was repaired at one point but rusted out again. It isn't worth it for me to mess with again. When the GC is running good, it is a blast to drive. It would so through just about anything.
I have had the engine shut down issue for 8 years now and considering everything I have done I am convinced that it cannot be fixed. I honestly think only a god could fix it, and I even question that.
I'd be scared to drive it anywhere. I had my Jeep turn off on I-30. Luckily I was on the right hand lane and could just pull off the road and wait until it would start again. Then it stopped a few times in the middle of town at a red light. Had a few people honking at me that time. I was happy to find the fix for mine.
I went through the same thing.. for a long time... it started with cutting off while I was driving.. then weeks later it did it again . Random, right out of left field, then it started happening every few weeks then Every other week .. Every day....10 x a day.. I replaced almost every thing attached to the motor..lol.. then it happened again.. that's when I said enough.. Jump to moral of story... I FIGURED IT OUT . IT'S A MANUFACTURER DEFECT..
My 1995 grand Cherokee jeep keeps shutting off when I shift gears while going low speeds. I don't know why it keeps doing. I can still turn the car on but it shut off when I shift. If anyone can explain why please let me know.
@@homestead_diy It has a shifting gears on the bottom. To where you got to put your foot all the way down on the brake then grab the shifter and put it in overdrive is what I normally do. It might have to do with my overdrive because my dad says it doesn't work well.
Agreed. But I have had instances where some places keep thinking they know what the problem is. So I keep paying for labor and parts and still don't get it fixed. But this time it worked out great...
There's a reason why I own a multimeter, code scanner and a fuel pressure test gauge. I did a look up on the part number you provided made me laugh as soon as it showed it having 4.0 engine. This engine is used in multiple models and years, and there are those who could've assisted you had you asked them. Doing a web search would've provided you a link to a Jeep forum that would've provided you the solution as well. Don't be offended, your just not Jeeple. 😜✌
good thought but didn't seem like that was my issue. I've got the same stock gas cap from 20 years ago and it is working fine now. Well as fine as a 20-year-old vehicle will work.

What is the name of the sensor?
What sensor
@@ashurienm Sorry, crank sensor, I edited the original comment to clear that up now. Better late then never, I guess.

Yeah, I've had cooling issues with this Jeep quite a bit. Granted it is almost 20 years old, but it seems like the issues have started piling up.

Thanks for the suggestion.
It wasn't fuel pump, spark plugs, wires. It was a throttle sensor, and an absolute pressure sensor .
It was just weird for me. The symptoms kept pointing to the fuel pump. Just glad I didn't go through the trouble of swapping the fuel pump.
I'm having the same problem with my 2000 jeep grand cherokee laredo it runs for awhile then shuts off I have to wait about 20 minutes before it starts again I'm going to replace the crank shaft sensor today thanks for the information
Hopefully that fixes it.
Did it solve problem?
My WK hemi was the crankshaft position sensor, start up on first try everytime now.
Glad it was something fairly simple. To be honest I had never heard of that sensor before.
Minds doing sane things
Mine just died, I turned the key off and restarted it no problem. A few days later it died and could not get it started. Ended up being a large plug behind ECM coming loose! I replaced the crank senser before finding this problem!
Thanks for the tip
Can you tell me what large plug are you talking about behind ecm?
Mine died while running it cranks but no luck
TIA
My 2007 Jeep Grand Cherokee 4.7 & 2014 Jeep Grand Cherokee 3.6 both does the same and mechanic still at a loss
Hope you are able to get it resolved. It makes the vehicles pretty much unreliable.

Hope someone is able to figure it out for you. Mine got worse and worse. It got to the point, that I didn't want to leave the house with it.
It's a straight 6, no V6 in any WJ JGC

These days people are assholes!!!
They have zero need to honk the horn just because you break down!!
So you figured out what was going on?
I went through the same thing.. for a long time... it started with cutting off while I was driving.. then weeks later it did it again . Random, right out of left field, then it started happening every few weeks then Every other week .. Every day....10 x a day..

Jump to moral of story...
I FIGURED IT OUT .
IT'S A MANUFACTURER DEFECT..
I had the same thing happen to me. I replaced the fuel pump and then found out what the real problem was, it was a bad computer.
Yikes. That sounds expensive.
Yikes. That sounds expensive.
No problem, I'm sure someone else will have this same problem..

Is it an automatic? Or you mean manually shifting gears? Sorry I doubt I can help, but asking a clarifying question for anyone that might can.

Worth paying forna diagnosis. Nothing worse than the parts cannon and its still not fixed.
Agreed. But I have had instances where some places keep thinking they know what the problem is. So I keep paying for labor and parts and still don't get it fixed. But this time it worked out great...
Mine was behind the ECM, it could be above it, but there is 2 large plugs, my problem was the larger plug
Thanks
This happened to me. Almost ran into a building. No one could tell me what was wrong with it
Yikes. Did they get it fixed finally?

thanks for the response. It is funny how many posts on Jeep forums where people have the same issue.
Gas cap
good thought but didn't seem like that was my issue. I've got the same stock gas cap from 20 years ago and it is working fine now. Well as fine as a 20-year-old vehicle will work.
Shit I was thinking it was my pcm
Have you fixed it yet?
Thanks I have a 2004.
This and overheating issues have been the biggest problems I’ve had. I’ve got around 160k miles on it
