Cumins isx 15 NEED HELP AND ADVISE

[smorgan87]

Let me be a bit blunt. Ur mechanic is prolly a damm idiot and shouldnt be allowed anywhere near an isx engine. Take it to Mr Haggai in GA so he can clean the engine out and rebuild it along with the pump and fuel system. After hes done with that he can redo the demandate so ur engine runs properly. Its almost like the engines telling u whats wrong with it and these half ass wrench turners are too damn dense to listen to it. Theres a reason ur losing fuel psi and that reason is likely because ur damn pump is shedding parts right on schedule. Now u can either take our advice and take the truck to one of only a cpl shops that knows wtf they're doing or u can take it to ur "reputable shop" and keep getting ur money taken to f&*k ur engine.
