So a little more to the issue, when it does go dead peddle I notice it’s not a true “dead” peddle. I still have full rpm range when I pull it out of gear and rev it up but it’s a little slower to rev up like a little loss of power but still revs. I can put it back into gear an that’s where it’ll fuel still just not enough to gain any speed but can almost maintain speed somewhat. Now once i cycle the key then it regains full power to where I can actually gain speed like normal. Sometimes it take 1-3 cycles an it’ll drive normal for 10-15miles but other times it multiple cycles of the key to eventually drive normal. Also if I’m in gears 1-4 an it does it I can just keep the pedal down for 30sec to 1 min while it’s “dead” pedal and 9/10 it’ll regain power an take off but it will not do that in 5th gear.

Wait to start comes on immediately, the mV shows 14.5-24.5 depending where I place the ground side of the meter, the dings I’m assuming is a code being active an yes it does have a check engine light on constantly. Unfortunately I do not have a fuel pressure gauge right now but it acted the same before and after a fass was installed.

So you think it’s a fuel pressure issue? It just seems like something electrical is cutting out, but something that requires like a electrical reset. I have 3 known good tps’s an no change in issues with any of them

Recently bought a 99 Cummins 4wd 5spd, my issue is the truck will get a “dead pedal” while driving. I can cycle the key “fast” or engage an disengage the clutch an regain fueling for 5-10miles and will get the 3 dings an lose the pedal again. From what I see the vp is a reman. I cleaned battery cables and replaced the tps and did a calibration with no fix. The previous owner installed a fass in hopes to fix the issue with no luck also. Truck starts every time no issues. Current codes are: p0216, p0122, p1693, p0222 and also have a code on body: module hardware fault.
