Hello, I'm hoping someone can help me with the problem I'm having. I've got a 2008 Dodge Ram 3500 6.7L and the engine light keeps coming on and the msg centre says to see dealer. I've got a code reader and the 2 codes it keeps showing are P000f (fuel system over pressure relief valve activated) and P1011 (fuel pump delivery pressure too low). The fuel pump was just replaced a couple weeks ago and its still giving the same 2 codes. The engine and emissions system is 100% stock and I don't have any type of power programmer. Anybody have any ideas on what else it could be? I've got over 317,000km on it and this is the first issue I haven't been able to figure out. I'm hoping someone here can help.
