I have a friend with the a 98. 5 Cummins, he has 275 injectors, a 35/40 turbo, Raptor RP-150 Fuel Pump (150 GPH) and a Quad-adrenalin, he keeps throwing a P0253 (M) Fuel Injection Pump Fuel Valve Open Circuit Problem sensed with fuel circuit internal to fuel injection pump. When this happens you can feel a dead spot while driving, if he takes out the Quad-adrenalin the dead spot is gone, and the rig runs fine, any ideas on this, or is the injection pump on the way out.
