Yep, it would give the Jeep the heart of a Lion this July.

 

I'm not looking to start a Apple fan boi vs Windows fan boi vs Linux fan boi flame war but that statement runs counter to my experiences. I'm running Snow Leopard (Mac OSX 10.6.7) on two laptops and one desktop. I restart them once every week or so, otherwise they are up and running or in sleep mode. After starting with DOS 3.21 I gave up on MS at Vista. Digital life is much more peaceful now. It just works.

To the OP please post up what the dealer finds, good luck. I betting on a rest by pulling the neg batt lead for 10 minutes will do the trick.

 

Yeah I will definitely let you guys know the outcome, if it weren't raining as bad as it was yesterday I totally woulda tried more on my own, but I'm lazy, the dealership was closer than home, and the warranty was money in the bank hahaha

 

No, my problem was a bit more complex, but sounded exactly like OP's. The Jeep has an anti-theft sensor for the key. If that sensor detects an improperly coded key, it will let the Jeep start and run for about three or four seconds, then die. I know this because I had an incorrect key back in the day when all of the locksmiths were uncertain what key the JKs actually used--early 2007. Anyway, that is exactly what my Jeep was doing a few weeks ago. Even push starting it--it would run for three or four seconds and even start to accelerate, then the engine would just stop running. Resetting the battery connection took care of it.

 

I'm on my computer now, not my phone, so let me key in on this description since it's easier for me to quote it now: If a vehicle doesn't turn over, that means it is not cranking. Turning over is the term for the starter cranking. If it doesn't turn over, then it's the battery (or connection), or something wrong in the starter system (including the ignition switch).

If the vehicle cranks (turns over), but won't start (that is, the engine doesn't start running and keep running), then you look past the battery and starter system. The three things you check are air, fuel and spark. But, with the JKs, there is a ringer (actually, with most modern vehicles). That's the anti-theft system. It is designed to shut down the vehicle if it is started with a key not properly programmed for that specific vehicle. This is even if the vehicle key is cut properly. It does this by shutting off the ignition--loss of spark and fuel (electric fuel pump). You should recognize that the anti-theft system has engaged by the rather innocuous red light that comes on by your fuel gauge. It is not labeled--it is just a small red light, and it is very easy to overlook it in the heat of the moment of your vehicle not starting. That is basically what happened to me.

If it's not the anti-theft system, you're into a bit heavier troubleshooting, involving insuring you're getting air (check the filter if it's suspect), you're getting fuel flow (disconnect the fuel line and see if it pumps out), and you're getting a spark (remove a plug and ground it with it still connected to the plug wire and look for the spark--be careful not to get a pretty good high voltage shock while doing this!!!). Figure out which one of those is missing and start tracking back to what's causing that.

If you have air, fuel and spark, you're looking at more serious troubleshooting--it's probably time to call a tow truck to get it home or to a garage.

 

Dont laugh . Try unplugging your eletronic sway bar at the sway bar . It happened to me .

 

Ok drum roll please...

I picked my baby up last night and here is what they said on the maintenance sheet:

The technician checked the codes with WITECH, has code P2111. Performed diagnostics per sheet and test passes. Cleared code and road test, vehicle will not accelerate over 40mph. Returned and checked for codes, no codes found. Perform ETC Relearn Procedure. After Relearn, getting codes P2115 & P2116 for acceleration pedal sensor. Can see pedal sensor readings changing with pedal movement. Perform tests per sheets. Replaced PMC control module and program to vehicle and Relearn ETC. No codes after repair. Internal failure of PMC. Road test, vehicle will still not accelerate past 40mph. Check for codes, no SPTORED. Perform visual inspection of all sensor connectors and found water in crank position sensor connector. Blow water out of connector and add dielectric grease. Road test, vehicle performing properly.


So thank you all for your advice and suggestions, you guys are awesome on here and probably do this kind of thing for everyone, but this is my first Jeep and I gotta say it feels like one big family, from waving to each other on the road to help like this on a forum, never got this with any other vehicle I've owned thanks again everyone!!! Time for a Sunday drive sans doors...

 

Do you know where that connector is located? I'd like to waterproof mine with dielectric grease NOW! TIA

 

No I have no idea, the service department was closed when I picked her up, but the dealership isn't far from my job, if no one on here can answer by tomorrow, I'll stop up there and ask and take a pic of it for you

 

Last night on way home ran through 2 giant monsoons of puddles about 1-2 minutes later as i went around a turn almost home as i hit the gas my jeep started bogging out. figured i had got something wet and just needed to let it dry next day went to go start it, and it would turn over but wouldn't run ran through checking fuses, air filter, disconnecting battery, and the list goes on. started reading these and several other threads trying to get some idea something silly that i missed i read this one, and then googled where i could find the crank position sensor. while i was under i noticed the insulator or heat blanket not really sure what it is was laying on what i thought was a wire the heat blanket or whatever it is was saturated completely and the more i looked i realized it was my fuel line i trimmed the blanket up, and she fired right up. something so simple. i just wanted to share so if anyone else runs into this they might not get stumped or discouraged and go spend a bunch of money for something they could have taken 5 minutes and fixed themselves.
