Have a monster 2 vp this is a pull truck. Have a code p0253 which is fuel injection pump fuel valve open circuit. Any idea how to solve issue or does the pump need sent in? Cleaned the plug on injection pump worked for about 30 feet then back to this half power bs. Any advice is appreciated thanks.
