Hauled truck to Ford dealership and had it checked. They are telling me that the pump is bad. But he could not tell me if it was the one on the frame rail or on the motor. They told me it would be around 938.00 parts and labor also included in that was cleaning of the turbo and some turbo boots. They said it had some soot build up in it. I'm not to familiar with that so hopefully you guys can give me some insight. Also if it is the injection pump is their any upgrades that I could do such as different style of pump etc. Thanks, Jimmy
