What is your question?
Warning light came on at start up. Did not go off as normal. Truck runs normally, 19-20mpg during rest of trip home. Where should I start troubleshooting this problem?

There could be many things causing that light to come on. A good diagnosis from a quality Power Stroke 6.0L Diesel tech is in order. These are complex machines that are well mastered by experienced technicians. Without knowing what codes are in memory and performing other necessary physical inspections, you really cannot recommend a whole lot. Good luck!
