Truck shuts off from lack of fuel to injection pump/injectors. Replaced the block mounted lift pump and fuel filter. The preheater assembly was permanently removed as it is a known source of air leaks into the fuel system. Fuel lines were removed and cleaned then put back on with new clamps. Truck started and ran great for 2 days. On the 3rd day it ran for about a mile and then died and would only start by priming the lift pump. Engine will run for about 5 minutes but then runs out of fuel and shuts off. The fuel filter was removed and checked again and appears clean. While the filter was off the key was turned on and fuel came pouring out of the fuel filter housing. I was not aware that these trucks had an in tank pump as well as a block mounted lift pump and injection pump. With 3 pumps and no fuel leaks this engine should have no reason not to run.
The fuel shut off solenoid also appears to be working as intended.
have the same problem?
