This is not what I wanted my first post here to be about...

So...

My wife was driving her 2 month old Rubicon home today in stop and go Houston traffic and it died on her. She tried to restart it, but to no avail. She called me and we strapped it out of traffic. It gave no trouble codes, did not shudder, no check engine light, it just died. It turns over, and if it catches it will run for about 30 seconds and die. Well run is a realtive term, runs like it has about two cylinders firing. Anyway, the dealer came and towed it in and will look at it in the morning....

We will see what happens.

Its a 4 door with the auto tranny. My wife says it has been doing "weird" things when she starts it with the remote start. Things like the power windows wont work untill the jeep is shut off and restarted or the A/C compressor wont come on until it is shut off and restarted. Other than those gremlins, it has had no problems...but, she did remote start it and let it wrm up this morning because to us South Texans it was cold this morning ( 47F ).

Sorry to hear about your gremlins

You'll find that the electronics on the JK is loaded with gremlins. Chrysler and their vendors suck. Your JK is an awesome offroad rig though. There are people on this forum that are much more electronic and computer savy than I. If you search you will find threads that address some of the electronics issues.

I recall another article where the plugs had got all smashed in and caused troubles with firing. I forget the cause however and the soultion. Might want to do some searching on Plugs on the other site and here to see if you can find. After reading you thread it looks really simular so I'd ask the dealer to pull the plugs and save for you if they are defective.

I figured that also could be it after seeing that thread, but it seems like a very uncommon problem, and one that may possibly relate to the supercharger. Very interested to hear what the dealership finds. FWIW- There have been some jk owners that have referred to the "stall bug". i am not sure what TSB it relates to or any of the criteria involved- models/ year(s) affected/ autos or manuals/ etc...

Keep us posted.

Here is the thread I was looking for. As usual on this site

http://www.jkowners.com/forum/showthread.php?t=3429&highlight=plugs
They are evidently still going through diagnostics as of 10 minutes ago.


I would say a bad fuel pump before I would say bad plugs.

My only basis for this would be that I would see that bad plugs would cause a rough running condition as the thread talked about rather than a total no start condition. It actually does act like it was run out of gas.

It is under warranty, it is a pain but not a major inconvenience, so I have the time to make them fix it and do it right. In the mean time the wife and I car pool to work, something we have been meaning to start doing anyway.


I will let y'all know as soon as I know something.

FWIW I had a fuel pump fail recently and around here in Corpus Christi we've had 100's (if not 1,000's) of vehicles have fuel pumps fail recently. It seems to effect all vehicles, new and old. My wife's had two fuel pumps fail this year on a one year old vehicle.

I've heard of Fuel pumps issue in all makes and model vehicles esspecially marine motors as they tend to sit more. The new gas is killing them constantly and if you let sit they tend have more issues. Since it's partially firing It's a hard one to diagnos without vehicle in hand.

I've been letting the boat, jetski, Lawnmower sit with the gas but with a special additive that is suppose to help improve the life of the gas we now have to put in the vehicles. I have been adding fuel injector cleaner every 5 k and it seems to improve the idle. I'm at 38K and started around 10k becasue it seemed to be idling worse. Even the Jeep tech said it seemed to idle a little rough but that it was normal. Idiots.

We have a winner...

The dealer said it was the fuel pump that died and that they will have it back to us tomorrow.
I asked if I could have the old fuel pump and they were very hesitant. The side of me that does failure analysis as part of my job would like to take it apart and see if it was contamination, bad seals, overheated, deterioration, etc.

It is really not that big of deal to me other than they were very hesitant. That kicked my "what are you hiding" mindset into gear. It's really not worth the battle. It would be a statistical sample of one and would not necessarily prove anything.


We will pick it up tomorrow after I get off work...I will give another update then.

The dealer will have to hold onto the part for at least 30 days (depending on the mfg's warranty parts return policy). After that, he might be inclined to return it to you. Just make sure you see the parts tag and match the VIN when you get it back.

Agreed with Chris Hansen, I am a Honda mechanic, and if we do a repair under warranty, we HAVE to hold onto it for at least 30 days, or Honda will debit our dealer for the amount of the part plus shipping if we can't send them one. So, when we have a warranty part to return to the parts department, we get the parts guys to sign our ticket and stamp it so we can blame it on them when it's not found!! C.Y.A. is my motto (Cover Your A$$).

I'm glad that they figured out what the problem was. It did sound like a fuel pump problem, but without the Jeep in front of me, it's hard to diagnose something like that. Keep us posted on how everything turns out.

Explain me this...

So the dealer called and said the jeep is ready and I don't owe them anything ...except for 5 Gallons of gas. I know that the they are technically supposed to drain the tank to replace the pump. The jeep had 3/4 tank when I dropped it off. My feeble mind thinks that is what it should have when I pick it up and it should be free of charge. Maybe someone with a little more insight can explain what the carge will be for and do it before I get there this afternoon and go on a small rant.

Am I missing something???
