Last year I started getting a dead pedal and, checking the codes, a P0216. The power went away and came back a few seconds later. It would happen once or twice on a five hour trip. The fuel pressure on my Edge showed 10 - 15 PSI so it was getting fuel. I parked the truck over Winter and this year it was fine until I loaded the camper and headed for the BC interior. I've hit a hill in 4th (and low RPM), no power so I downshifted and off I went. After I got back I had the same dead pedal -- you could hear the engine defuel -- and then it came back a few seconds later.
I took the truck into PDR Diesel in Langley and they installed a Bosch reman injector pump. The mechanic took the truck out for a test drive and ... dead pedal, P0216. So they checked the APPS, checked the PCM, brought in a Chrysler tech with a Chrysler scan tool and did a deep scan of the system. Nothing. So they decided to do a volume test -- maybe the fuel pressure sender was wrong -- and they found air bubbles in the fuel. Not enough to make the engine run rough but enough to make the pump throw a timing fault once in a while. They ended up dropping the tank. Whoever installed the FASS system years ago did a poor job removing the in-tank pump and adding a draw straw.
So my original VP-44 still had a few miles in it and the real problem was a bad connection in the tank. I should have gone back to basics and started with a volume test even though the fuel pressure was good. At least the new pump should last a long time. The truck has 122,000km (75,000mi) so far.
