cummins not starting
so i got a call to help a friend with his 99 3500 5.9 24v 4x4. he drove it home shut it down and it wont start now. the lift pump is running like it should. i have yet to check the pressure at the injection pump. will do that in the morning. fuel filter is new and i have fuel pressure at the injectors. now here is where i am fearing the vp44 failure. i have codes p1688 death code, p0253 injection pump fuel valve open circuit, and p0251 injection pump mechanical failure fuel valve feedback circuit. please tell me the vp44 isnt dead. i dont feel like shelling out 1000 bucks. i told this guy i would fix it if he gave my wife one of his horses.
