Question about 2004 Dodge Ram 2500

1 Answer

Difficulty starting 1990 Dodge Cummins.

This has been the startin'est truck I've ever had and Ive had it for about 14 years. It only has about 175,000 miles. Recently it acts much like schmalfarm described. I already changed the lift pump, which made no difference; then the fuel filter and water separator. The latter helped a lot, but it still acts a bit like you would have run it out of fuel and then not bled it properly. I have pinched off the return line and let it sit for several hours and then did the same with the supply line. Made no difference; evidently it is not bleeding back, and I can see no leak.
What could be the problem?

    Don't think it could be the glow plugs. I normally did not use the pre-heat except in cold weather and it fired right off. Now the weather is hot.

My 5.9 dodge cummins diesel won't start, I've replaced the fuel lift pump, and the fuel filter, turns over. But will not start?

Most likely you just have air in the lines.Crack them open one at a time and bleed them with the fuel pump off and on till you get fuel.If it fires dont hit the throttle let it sit and idle and close the line.Does it fire up with a small whif of starting fluid?

Google the cummins forum online. They have many people with similar problems as you. Maybe it will point you in the right direction. Could be your heater coil going out.
