I don't know if the entire question posted so i will just repost it here. Sorry. I have a f350 super duty diesel that the fuel pump went out. I changed the fuel pump and now have fuel in the bowl. It still wouldnt start. The cps is good. The heater under the fuel filter was replaced. The high pressure oil pump has oil in it. The coolant is full. Unplugged the oil pressure senor off the rail to default the cpu and it still doesnt start. The glow plugs are heating the tack needle moves when you try and start it. I dont know how to test for pressure on the rail though. If i pour gas on a rag and put it at the air intake it starts but no throttle control and it dies when the vapors are gone. I need help! Any ideas?
