Truck has a 7.3 and is a 4x4 dually. Took too a job site and shut it off for 10 minutes and it wouldnt start. Have been told may be a ground wiring issue since the problem is no power to fuel pump. Replaced many sensors and a new computer, no need to mess with it anymore. Frame is solid, no rot at all. Truck over all is in good shape. Box is about 3 years old and works great.
