05 2500 wont start without ether. Once its started it will run all day as fast or slow as needed and idles fine. Once you turn it off wait thirty seconds, wont start. I took to dodge and they say injectors but these injectors only have 60,000 on them. Also had to replace fuel pump because it kept blowing at the return on the pump. If it were injectors it wouldnt be putting out that much pressure. I have been told injection pump or fuel pressure regulator from different people, any ideas?
