Truck will not move on its own power

[satwide]

Hey guys,

I have a 99.5 powerstroke with 67,000 miles on it that cut out and went to idle but, no acceleration. Eventually the power came back until this last time. Now I have a slightly rough idle and lacks power (will not move on its own power). I haven’t seen any signs of colored exhaust. I have changed the oil, fuel filter, and cps. I also removed the hose from the turbo and checked to make sure the turbo spins freely. The check engine light comes on but will not register a code. I have had three different OBD-ll scanners on it and no codes. If any one has any suggestion on things to check I would greatly appreciate it.

Did you change the oil before or after this happened? the weight of the oil is critical to the injectors and you need to use what ford says to use given your climate. also ensure your fuel injector harness (usually wraped in red tape) is fimly pluged into the valve covers.

I changed it after, but with the same grade synthetic rotella t. I will take a look at the injector harness. Thanks

Yes it sounds fuel related to me. A guy i know had his injector drive modual go down. The motor was only running on one bank (4 cylinders) This is also another area to look into. Good luck!

have you checked pending codes on a scanner

Did you figure this out?

It sounds like your truck is acting like mine. Did you figure anything out with yours?

Sounds just like you are running on 4 cylinders like mine this week. Lost power and a little white smoke. Auto Zone computer couldn't read a code although check engine lite on. Friend with school bus barn computer came up with #5 or 7 injector. Snap-on computer zeroed in on #7 injector. Problem was when #7 shorted out it took out the IDM. There is another thread on this site about unpluging first the right then the left IDM. You might want to try that. If you don't have friends who are diesel mechanics.

Ahh this is EXACTLY what happened to my E350 today! but it was some what intermittant. It would go from running perfectly smooth then Click.. it was coughing and sputtering and hardly moving on its own power! then click. it was fine again and back and fourth several times over a few mile drive threw the city! I was thinking it was electronic. any suggestions?

Check your UVC harnesses.
