The wiring that runs around the valve cover in the back was sitting on a bolt and had rubbed through. Rubber tube was put on bolt to keep from rubbing wire and causing short in MAP sensor..
I think the problem is with the PCM.
If your fuel pressure is readind what its supposed to , check your plungs and wires and if that looks good check your mass air flow.
I think I had this same sensor replaced about 5 years ago.
A week later I took it back to the shop and they replaced the spark plugs thinking that might be the problem since they had never been replaced. Now another week later there is still a miss in the engine and I think it may be getting worse cause it took longer to start this morning.
Any thoughts as to this problem?
After that it had a miss so I took it back, and they replaced the plugs, still had a miss, took it back and they replaced the coil and O2 sensor, still had a miss , even worse, so bad that I don't see how he missed the miss, took it back again and let them have it!
They replaced the crank position sensor AGAIN.
Now it's working but there's still just a very slight miss that only the driver might notice.
I feel like they didn't really know what they were doing and just replacing things hoping to fix it.......at my expense.
I'm tempted to call the owner and talk to him about it.
Do you smell anything peculiar just before or after it stops? Any strange noised as it dies or when you are trying to start it? Have you notice the gauges (the instrument cluster) doing odd things? Suddenly the fuel is totally full or totally empty? The heat gauge is totally hot to totally cold? How many miles are on the vehicle? What year, model and engine option do you have? Sorry to ask so many questions but for me to be able to evaluate the problem I really need a lot more details to work with. If anyone else knows what it is from the description, please jump in.
good luck
-Happy Wrenching Guys!!
FML!!!
I have seen other posts concerning this where people just pulled a fuse, some said it was a fuel sensor, some said to reset the computer - all sound cheaper than $1,600
If anyone has had success fixing this problem, please let me know. Thanks!!
TIPM won't come in until August 22nd so they approved a rental car. At Enterprise Rental for [non-permissible content removed] and giggles I said hey, you got a 2014 Jeep Grand Cherokee I could have and he said yes except it is back at the same Cherry Hill Triplex Service department because it won't start. What is going on here, everyone please post your no start problems, I believe there is a cover up going on and Chrysler needs to man up and do the right thing for us.
TIPM is on back order until August 22, 2013 so Chrylser approved a rental car. At Enterprise Rental I asked If they had a 2014 Jeep Grand Cherokee I could have and to my surprise they said Yes except it was back at the same dealership; Cherry Hill Triplex because it won't start! Same exact problem, what is going on here? Search the internet and I find too many same related issues, Chrysler must know they have a problem on their hands and are not doing the right thing by us loyal owners, this is my 5th Grand Cherokee and I always loved them, I just never owned them this long, I was lusting after the 2014 SRT with that Launch button but now I'm rethinking everything. This story is still live and I will continue to update it, Please everyone post your no start problems, there could be something much more worse than we know. jmelville@tristatehvac.com
Check the TPS (throttle position sensor), This can be a bear to get to, long thin arms and a good sense of feel are good to have for this job. Two bolts top of the flywheel cover. Usually has a lot of grease and dirt build up. This sensor helps in determining the timing of the engine. If it goes bad it will produce the symptoms you are describing.
A bad ignition coil can produce similar results too.
or if your cat cvt was not replaced during the exhaust work, look there.
The Jeep customer service people told me today the part will ship on September 23rd. They agreed to pay for a rental today, only on 5 day increments. I don't really follow that logic.
The dealer told me the part would cost $1153, elsewhere on the web it appears the correct cost is $600. I feel I may be getting taken advantage by the dealer. The vehicle has 62,000 miles, the transmission is starting to slip and the sunroof has leaked since day one.
Never again, I am all done with Jeep/Chrysler.
They told me the part would be $1,033. Mine is a JGC Larado 4x4 5.7, but I don't think it matters what model you have. This problem seems to affect any Jeep Grand Cherokee, especially 2011 models once they pass 40k miles.
I think there are enough people on here to get a class action suit started. For me it is inconvenient and dangerous so far, but to those that have to pay out of pocket because they have no warranty, this is even more serious. I hope no one gets hurt or badly stranded.
This is serious ridiculous! Who knows how long it will be until this part is fixed and available again!!!!
Any owners out there as a sad jeep owner that want's to take on the mighty giant Chrysler? I think we would have better luck if we all write to the National Transportation Safety Board and keep telling everyone you know about this problem on all the social media networks.
