My truck has not had boost pressure when towing several times on our trip. Previously a rap or two on the turbo charger would restore boost. A day or so ago near Tupolo, MS I had no powet when towing, no boost and raps on the turbocharger would not get it back. I disconnected the truck and drove into Tupolo.

There was heavy black smoke, high EGT, no power, and the truck would not go faster than 25 mph with EGT at or over 1200! I stopped to make a cell phone call and left the engine run. When I drove off I had boost, normal EGT and power!! The local Dodge dealer could not find any bad codes, fuel pressure, waste gate sticking, or any turbocharger malfunction! After a hour of work they decided I had a bad case of "beats me" and sent me on my way. (No charge.) Here is a dealer I woudl go back to.

I am approaching having to throw parts at the truck until one of them fixes the problem. So far the Phoenix Dodge dealer replaced my fuel transfer pump to fix the problem (it did not). Two other Dodge dealers were unable to find anything wrong. Something is sticking, or failing to work, and then starting to work.

Any suggestions?

 

Can someone with power move this thread to the Diesel forum? I think it would get a better response there.

Either that, or check out this site...

Good Luck!
