#162 of 213 Liberty has a hard time starting by chapusin

Sorry to bother all of you but I must tell you the problem I'm having and hopefully somebody can help.
 
My jeep liberty 2002, 107k miles is having a hard time starting after hours of no usage, sometimes just enough to cool down the car, say, 3-4 hours. The car tries to start and dies immediately, the only way I can make it work is by accelerating to 3k-4k rpms, hold the pedal down for a few seconds, and then let it go.. sometimes it will stall and turn off and I have to keep trying, and sometimes it will stay at idle, after that, if I drive it and turn it off and on again, it will turn on like nothing ever happened, the mechanic changed the MAF sensor already though the computer is not giving out any codes, to the computer the car has nothing wrong and also I took it to another mechanic and told me there was nothing wrong with the car. I'm very afraid it will stall on the road like it's happening to you guys.

I've got an 05 Liberty CRD that has stalled three times in the last week--all at the same stoplight. In addition, it frequently has been having a problem maintaining idle RPM when slowing to a stop. Seems to have no relation to warm-up time. No dummy light on. Have added fuel since start of problem. All fuel from usual source. When not experiencing the problem, seems to run fine. After each stall episode, it started readily and ran okay, with no further problems during that trip.
 
More details re: specific trips on which engine stalled. Each time, it was on afternoon drive home from work. Pulling up to stop at stoplight approximately 1 mile from workplace, engine stalled at almost exactly same moment that vehicle came to a stop, all three times. Have almost stalled a few other times, but have also pulled up to same light, same circumstances, with no problem.
 
No significant repair history for engine problems to speak of. All routine maintenance done per manual.
 
I see above mentions of "throttle body" problems, cable routing problems, fuel cap problems, and more. It's NOT the fuel cap, as best I can tell. There are no other issues with faulty speedometer readouts or the like, and I can't imagine why a cable problem would be so specifically intermittent, so to speak.
 
I've got an appt at the dealer's service dept. (please pray for me!), but I'd like to have some idea of what the problem is before they charge me an entire Obama stimulus package to (maybe) fix it.
 
Any ideas, suggestions, etc. are welcome.
 
Thanks

Get a new fuel filter. Wix Filters are 1/2 the price your dealer will charge. Find a truck driver that drives or owns a diesel [pay if you have to]. Before the new filter is put on your CRD fill it with transmission fluid. The transmission fuel burns hotter than diesel oil and will get the carbon out of the CRD. I carry a WIX fuel filter always in my '05 Liberty Ltd. and have had your problem.
A bad battery will also cause similar trubble.

Hi,
Is your engine already warm when it stalls coming to the stoplight you describe? I imagine your transmission oil is also "not yet at temperature".
Try engaging the "D" position on the transmission and hold the truck for a minute by applying the brakes: this will warm up the engine, cabin heater and transmission.
It works for me, so nowadays I let the engine run a few minutes while I get rid of the ice and snow off of my wife's vehicle and I don't disengage the transmission while waiting in the local traffic. 5 minutes later I reach the motor way with the engine warm and with the proper shifting sequence.

Sounds like you're saying the problem is basically a plugged fuel filter; am I understanding that correctly? Would be nice if that's it, since that'd be a cheap fix.
 
I really don't think it's a battery problem, given that the engine will restart immediately without difficulty, and it starts on cold mornings pretty much as it always has.
 
Regarding the Wix filter--you mention finding a "truck driver that drives or owns a diesel [pay if you have to]". Not sure I understand this bit at all. Why do I need to find a truck driver? Are these filters not available otherwise? What am I missing here?

"Is your engine already warm when it stalls coming to the stoplight you describe?"
 
Yes and no. It's now stalled--completely died, that is--four times. Each occurred within a mile or two of starting a trip. Some warm-up had been allowed for each episode. The warm-up time allowed for the engine during each of these circumstances varies from approx. 3 to as much as 20 min, all spent sitting in lot at idle. This last amount occurred as I sat in the lot, talking on my cell phone while the Jeep idled. [Call history says the phone call lasted 21 min.] I've not had the Jeep out on a trip of longer than about ten-12 miles in the last month, so can't tell you what it acts like at mile 45, say.

A new fuel filter is a cheap thing to try. I agree that this is a good possibility b/c I have had the same situation. I changed the filter and everything was good. I keep many on hand and change about every 5K. You can get them online if you don't want to pay the dealer price. Try, http://www.discountautoparts.com/

Now I'm up to four episodes of completely stalling, and the Jeep's at the dealer since 0700 today.
 
In phone call with tech this PM, I was told that (a) they didn't pull any codes from the vehicle's computer- when they hooked up "the Derby" to it to check for DTCs, (b) they couldn't replicate the problem when they drove it [of course not], (c), they'd been working on the scheduled maintenance (I'm doing the scheduled stuff same visit for convenience) and (d) I need new brake pads and rotors resurfaced. So, at 43,000 mi and change, I need new brakes (rear moreso than front), after replacing brake pads already at about 23,000, they don't know what the cause of my actual problem is, have little hope of figuring it out, and I'm considering trading the Jeep for a decent bird dog.

As I said above, I like the idea of a fuel filter being the fix. How would a fuel filter going bad lead to a sudden drop of idle when braking to a stop?

The valve that sets the fuel pressure inside the common rail could give you the same symptom taken into account that the engine is warm and suddenly unloaded by applying the brakes. Try not to use the A/C to see if there is a difference. How does your transmission pull on the engine when this occurs? Have you tried going into Neutral just as you come to a stop?
I tend to disengage the transmission because my engine pulls quite hard while idling cold: my driveway has a steady ramp of 25% incline and I don't need the brakes to hold the truck in place. If you try to push the Jeep on such a slope, you will better appreciate the power of the diesel engine when it idles; it has to choke or starve to die out.
