Had my CRD towed yesterday. It was the third time it would start up in the morning then shut off. This time it didn't start back up. Dealer called this morning and said they tested the fuel and found alot of water. I asked why the warning light didn't warn me and he didn't know if had a warning light. I had them drain the tank and lines in and install new filter on me of course($500.00). I had the fuel filter changed around 20,000 miles(31,500 on it now). Dealer saved some of the fuel they drained to show me how much was in the tank. Why didn't the warning light come on?
Just wondering if you had it parked outside below freezing?
In most diesel fuel tanks, the pick-up tube is raised slightly off of the bottom of the tank allowing for most of the water to settle without being sucked into the system. It is possible for some water to travel from the tank in suspension and wick into the filter element where it freezes when parked. It's not enough water to trip the WIF sensor but enough crud to give you problems. So, on a cold morning, it may fire at first but won't run very long with a frozen filter. This condition usually gives you some warning signs like it won't pull under load. If you find this happening again, try a shot of "Power Service 911" which is designed to clear this out and get you running.
My personal diesel maintenance rule #1: Change your fuel filter at least once a year in cold climates just before the weather freezes and if possible check for/drain any water from the bottom of the tank while doing this service. Unfortunately, Jeep didn't tap a drain in these fuel tanks.
