06 Dodge Diesel Engine Shutdown Adventure-UPDATE

I thought I would pass along my latest adventure with my now 10 year old dually with 250K miles. I have been fixing issues over the last year to keep her running strong and reliable.

On my last trip south about 3 weeks ago 25 miles south of Columbus, Ga the engine surged, then ran about another mile and shut down. I was in the middle of nowhere so I removed the fuel filter and after some fumbling around got it started and limped to next town about 10 miles down the road and bought the only two fuel filters they had at the only auto parts store in the small town. I put in a new one and thought I was fine. We made it about 20 miles to Dawson, Ga and it shut down again. This time I filled it with fresh fuel and a diesel fuel additive. I figured I was ok, but I only made it about another 30 miles and it shut down again. I had bought a couple more fuel filters so I replaced it again and eventually got it started and again ran fine.. until it didn't..

Anyway after one more event I got it to a diesel shop in Tifton, GA where they said I had trash in the fuel pickup assembly resulting in a drop in fuel pressure. The computer on the truck shuts down the engine when pressure gets to low. They said the removal of the filter released suction pressure on the intake debris and enabled fuel pressure to normalize , thus it would start and run.. until it happened again.

Anyway I finally dropped the camper, left it and the truck there at the Tifton shop and rented a car to finish my trip and decided to pick it up on the return trip. They replaced the fuel pickup assembly and apparently only screened the fuel and added fuel stabilizer, but when I picked it up it ran fine (perhaps a total of 800 miles) until...this last Friday afternoon when I was back home (this time without the camper running an errand). Truck shut down again and this time I had no luck getting it started. Had it towed to a shop to late in the afternoon for them to do a diagnosis.

I called the shop (while waiting on the tow truck) in Tifton and they still think it is probably trash in the tank and recommended steam cleaning the tank. I have located an aftermarket 60 gallon replacement tank that I am considering, bigger and more range than OEM .. but , could it be something else ? The truck was running GREAT.. smooth good power and then WHAM.. shut down.

Momma will not ever want to take the camper out if I have another outting like the one in South Georgia. Our final breakdown on the Georgia trip was in the pre-dawn dark while it was raining on I-75 and I was fortunate to get it to the Tifton shop without a tow.

I need confidence in the solution before the next long trip. The new tank will eliminate the trash variable, but are there any thoughts/advice you all out in Diesel Truck/TC land can offer ?? ( Oh, Please be constructive in your thoughts.. please don't advise me to get another truck, a different brand (Ford or Chevy or whatever. ) I am curious if any of you have had a similar issue.. and if it could be more than the trash in the tank. I meet with the mechanic where it was towed tomorrow..


Thanks

  • I gotta say, to clean a clogged pick up and not the tank is ridicules. There is more stuff in the tank than just what was on the pickup. Where does the mechanic think the trash came from?

  • what does the filters look like when you pull them, Black slime?

    if not, Maybe your in tank lift pump is starting to fail.
  • MrPhelps - what you describe is different from what I experienced last fall on a TT cross-country trip, but it is worth a check in the event your cause is a worse than mine similarity. Mine was an intermittent act-up like a gas engine would describe as a miss. Sometimes ran normal, sometimes a slight stumble/hesitation and sometimes an awful stumble. If it got any worse, it could have resulted in an inability to start. I expected mine to be injectors and yet it was worth checking what I did.

    There are about six separate electrical connections on the the fuel pump and filter areas. I disconnected each, cleaned with an electronic spray cleaner, reassembled with die-electric grease. It took twice, but the problem disappeared. It was poor electric signals telling the engine to do its thing.

    I also have a 2006 Dodge 5.9L diesel. Good luck.
  • Did you buy the truck new? If not, a previous owner might have installed a aftermarket fuel filter in line from the tank to the factory filter under the hood. I did that on my '06 in order to get the Cummins mandated 4 micron filtration they spec for this engine.

    Look under your truck, along the frame on the driver side, between the tank and the driver seat area for an after market filter. (I presume a filter under the hood would have been obvious.)

    A truck with those miles might have a filter that is blocking flow if it's not been changed because you weren't aware a past owner had installed one.

    Worth a try..

    Did they test for proper fuel pressures both high and low?

    Does your truck have that small cheap electric fuel pump on the back of the fuel filter housing like our 2004.5?

    If so, it could be that pump or the connections taking 12 VDC to the pump.


    My 2004 3500 Dodge diesel crapped out as I was going down the road. Towed it to dodge dealer, they removed the fuel pump from the block of engine and put it back into the fuel tank itself. No problems since:)
  • The 06 RAMs have the low pressure pump in the tank.

    Do you have a check engine light? Any codes?

    It does sound like something obstructing fuel flow.
  • Excellent advice gentlemen, thank you. I do not know if they checked both low and high pressures. Will check other issues noted in your comments at the shop tomorrow..

  • What the shop in GA told you about trash in the fuel pickup makes sense. The only way to know for sure if it's the same problem is to drop the tank and find more trash in the pickup. If that is the case, then maybe the new tank is your best bet. No trash? gotta start looking for another problem.
