No accident to report. I wasn’t aware of the problem with the High Pressure Fuel Pump intel a week later when the noise got louder, at first I figure it was the belt drive that needed check do to it sitting in the lot do to not being moved a lot. I then took it back to where the Vehicle originally came from they where able to identified the problem quickly to do them knowing already that the truck had that problem but never went to fix the problem or to take time to figure the problem out.
