Question about 2004 Dodge Ram 3500 Truck

Open Question

My 5.9 cummins is having fuel problems. (big surprise!) I replace the boost pump and it solved the problem getting fuel to the injectors. But it isn't lighting it. I have thought for the last year that my induction heaters were gettint weak. With the number of cycles that I put them through to prime the fuel system when I replace the pump, could I have pushed them over the edge? how can I test the system?

Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

SOURCE: dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

SOURCE: number one injector bank on 2006 dodge cummins

you'll notice on your valve cover gasket there is two connectors.. the one up front is your 1-3 the one in the rear is your 4-6... you can remove your valve cover and check the connections from the injector connectors to the
connectors on the valve cover.. check for an open.. however you could also have a fault internally in 1 of your injectors in that bank as well.. hope this info helped..

The "wait to start" light is your glow plugs. You must have a loose connection to them or something not connecting. They come on almost everytime you start them, hot or cold.

N14 cummins in a peterbilt getting large amounts of fuel in the oil. Replaced the pump heads and injectors and still doing it ?im told that is all it can be


Common problem on this engine and the current solution is to constantly change the oil to prevent overflow and then inter your DPF system if you have one.

One thing to try is have your computer re-programmed, but no guarantee it will solve your problem.

I ran a mixture of diesel and water thru my fuel system about three miles or so what do i do now


drain the fuel, change the filter, add fresh diesel. cycle the key several times and see if she fires up. you might have to crack the injector lines to help in bleeding the air out of the system. the good thing is the vp44 injection pump doesn't know what its pumping and 2001 24v cummins do not have electronic injectors, so you should be ok.

2003 dodge cummins had to start runs great when started. i changed the lift pump/cp3 pump/2 injectors and cam sensor still have starting problems.


does the truck have any active codes, what is the fuel rail pressure getting up to while cranking, why did you replace the 2 injectors, why did you not put all six in? did you do this yourself, did you follow the correct procedure and properly torque everything. these engines are very sensitive to proper torque on fuel components.
