RE: Fault Code 1117
Update: Tried running power directly from a new set of batteries I installed to the ecu didnt help. grabbed a gear fuel pump from the wrecker. Looks like a new replacement as it was not painted. Put it on the truck. Lift pump making a solid 14psi, new gear fuel pump making 350psi at high idle. Thought I had it fixed. Drove it with a loaded trailer like a bat out of hell for 20 miles over washboard gravel roads over rail tracks. Not a hiccup. Parked it left it idle, 15 minutes late its belching white unburnt diesel fuel smoke, like it does when it goes into limp mode. Argh. Next I want to try having Cummins Insite on it so I can catch the offending sensor or problem when it does that.

Ok so truck still the same issue. Runs great for a 30 minutes or an hour lots of power fuel pressure at the rail strong. Let it idle for a few minutes. Step on the throttle fuel pressure falls off to 120psi and white unhurt fuel out the exhaust no power. What is going on?

RE: Fault Code 1117
when it starts to do that release the fuel tank caps. Being it takes a hour or so maybe the tank vent tubes stopped up.....If thats not it look in tanks make sure theres nothing in them that may cause a restriction. Sounds to me the issue is lak of fuel and being it takes some time seems like maybe a floating blockage or tanks not venting.....
