Truck runs and idels great. Once out on the road and driving highway speed I will exit and come to stop now truck is still running but once I take off and get to 2nd gear it will sputter and backfire and won't pick up speed. Feels like its not getting fuel but I have already replaced fuel pump and getting good pressure. What could be the problem here?
