My 04 3500 Quad cab 4x4 automatic 5. 9 HO died again today. This started back in May. When it dies normally I can pull over and prime the fuel filter by turning the key for 30 sec. s. Most of the time I do this more than once. Then it will restart. Some times it will keep running for along time 400-500 miles other times it dies right away. I have changed the fuel filter which was clean, changed the FCA, checked for fuel leaks, etc. The codes I pulled the first time were P0483, P0148 and P0088. I cleared the codes and drove it for awhile more before it died again. I primed it and off we went. I took it to the dealer who was unable to find anything wrong. I drove it for about 2500 miles with no problem and then today it quit again. This time I had just P0483. I primed it and got it home. While the previous owner had the truck about 25K miles ago, currently has 50K he took it into a dealer for no power, it would barely go 45 miles an hour at full throttle. The dealer converted the lift pump from the filter mounted version to the in the tank version. Before he was able to get it out of the dealership they finally changed the fuel filter, which probably was the original fix required. What should be a running fuel pressure of the lift pump at the filter? Can the lift pump faill without producing codes? Where do you think I should start? I really have enjoyed the truck until it started being unreliable.
