As I am mechanically challeged (I barely know which end of the wrench goes on the bolt), Jim Jessup of Diesel Tune Up, North Vernon, IN installed a new lift pump, one of the $70 Cummins lift pumps, for $225. Jim worked for Cummins for 33 years and retired six years ago. On his card he lists himself as a "Cummins B Series Specialist". He has garages including dealers call him asking questions on how to fix a peculiar problems. I mentioned TDR and Jim advised Bob Patton tried to get him to wite some articles while he was still employed at Cummins and Cummins wouldn't allow it.
To further my story, on 10/9 on the way to work I had my fuel pressure gauge drop to zero, as couple of seconds later it came back up to 10. As I was leaving that Saturday for DC and was taking my fifth wheel , I drove to the dealer that evening to have ot checked out. I was told I hade a P0234 code which indicated a wastegate sticking. The dealer was told by Dc to clear the code, drive the truck and see if there was a recurrence of the problem. There was not until Moday.
I mentioned this to Mr Jessup . He asked how many miles I had on my truck, I told him 68,451. He then looked over the truck and told me that I did not have a sticking wastegate, the drop in fuel pressure caused the code. He further advised that I have a clean stock truck, less than 200,000+ miles, and said "there's nothing wrong with your wastegate". So my lift pump was bad then. It's only by the Grace of the Almighty that I didn't get stranded somewhere between Indianapolis and DC or on the side of one of those mountains in WV.
