Hi, I have an 01 2500 quad cab with 5.9 diesel. Been having prolems with intermittent dead pedal. Changed lift pump recently , no change, my local mechanic tested lp pressure and pressure was fine. "injection pump timing" comes up when scoped and cannot be reset. He sais he thinks that is injection pump needs replacement and I tend to agree with him from what I have been reading here and elsewhere. Can anybody recommend a good supplier for quality injection pump and maybe a performance fass lift pump to go with it. I have seen several online suppliers advertising but am unsure about the quality of the products. I live near Toronto Canada but would be willing to pickup parts in US if I was sure of the product and of course the price was good. Any recommendations?
