Ford F-250 Super Duty QuestionsRefine by vehicle
My truck was pulling a trailer 600 miles and begain to buck jump when coasting down for redlights to the point you could not remain in seat without seatbelt.
All trailer brakes were disconnected still same problem. After removing trailor the engine died and would not start as long as engine warm. After engine cooled, it would start but ran horrible until it warmed then it would shut down. Engine oil fine and oil pressure fine.
knocking noise coming from the air intake only at idle . it idles really rough to .no engine lights on or warnings
took battery terminal off now it starts but when put in reverse it idles up and down and spark nocks till it stalls could this be a computer issue?
The door locks and windows and ac don't work.
hard start in morning sometimes have too cycle glow plugs 2-3 times to keep truck running
problem just accured, not using it til Iget it fixed. replaced the ignition switch, no difference cant see any wires broke or rubbed, hoping for some insight
the check engine light comes on but nothing seems to be wrong it started this when I changed the batteries
We took it to a desile mechanic and he could not duplicate it. replaced both batteries, they went through all the wiring, The horn does not work, changed the alternator. What else ??????
The check engine light was on for about 20 minutes and it only does it when I speed up.
Once the smoke finally blows out it will run fine. Until I stop again and take off. ?!? It is a 6.0 power stroke
Was told to check inline filter and don' find one
Motor is real sluggish and have to stop and restart the motor. The its fine for a while until it does it again. Seems like it only does when it's rainy weather
Replaced intake gaskets, no change. switched COP's and no change.
Truck does not drive or shift differently. Will it harm the truck to keep driving it?
all light\s -air -etc work just no dash lights & when I stop At Stop sign it pulls away in 2nd gear!!!
In two weeks time, my truck has gotten worse. First was glow plug light staying on and no fuel flow when trying to start. Then last week started shutting off after first get going. Problem is getting worse. If I get all lights on dash (water in fuel light comes on and cycles off), glow plug light goes out and truck starts. If water in fuel light doesn't cycle on, glow plug light stays on, and truck will not push fuel to start. Cycle key over, doesn't always work, sometimes works. 2 nights ago, check engine light finally came on, drew 7 codes, which I don't have here as I type this. New GPR installed today though, so it isn't that now.
2 new batt ,new fuel filters new oil filters checked and confirmed fuel at top engine mount checked ficm 48 volt ,had starter benched tested good and replaced altinator also checked all pulleys cranks really slughish and sound like something holding it from turning over
