Re: f-250 superduty deisel in need of some help
Might be the injectors? Just had my 7.3 repaired, all 8 injectors were so plugged no fuel was able to go through. It would not start, unless pull started. rpm's wouldnt get high at all. Had the glow plugs replaced last summer thinking that was the issue but all the injectors were. Runs good now.
Good luck, I would try to find a good diesel mechanic.
