I took my truck to the dealer today because of the check engine light. It had a 1693 code showing on the odometer. The service manager just called me and said the VP44 needs to be replaced and theres a nation wide back order of 132 VP44's. He said 1 to 2 weeks for the replacement to get here. They did replace the lift pump about 3000 miles ago under warranty and even though I caught it early because of the fuel pressure gauge I guess it still damaged the injection pump. At least its still driveable and hopefully won't leave me stranded someplace. Sounds like it's time for a pusher pump to be installed but that creates another issue itself by tampering with the fuel system.
