Do fuel pumps go out immediately or will they cause the engine to sputter, similar to water in fuel mixture, and kick right back on again and the engine acts fine?
Example: I was on my way to work, truck sputtered like it had water in fuel and after about 1-2 minutes it was fine,but while it was sputtering i didn't know if I was going to make it to work. Left work, truck was fine. Next morning, it did the same thing again. Then on the way home, the truck sputtered and quit completely.
Pulled the fuel filter and there was only about 1/4 inch diesel in the filter. Am i looking at changing the fuel pump?

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.
This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.
Please clarify the "loosing power" does it lose power and shut down or does it loose power but will idle? Your Cummins is electronically controlled so oil condition is important, fuel leaks, oil leaks, leaks in the air ducting between the turbo and the intake, sensors, water in the fuel. Do you get an engine light when this trouble happens? Dodge uses a lift pump to carry fuel to the the injection pump, is it working?

I agree with kious75, you need to get the air out of the injector lines. Has the truck ran AT ALL since the installation of the injector pump?
What type of additive did you put in the trucks fuel tank?
Have you replaced the fuel filter recently? Check the filter canister to see if fuel has been pumped in to it. (one way to check is to open the water/fuel seperator valve on the bottom of the fuel filter canister and see if there is any fuel or water in there)
I had a 1999 Dodge Ram 2500 with a 24V Cummins ISB engine and had trouble getting it to start. Had NO luck bleeding the injector lines. My truck was a 5-speed so I got it on dry level ground and had a friend pull me with his truck, I popped the clutch in 3rd gear and the truck cranked up beautifully. It is similar to the process you would go thru if you had an old 5-speed vehicle with a dead battery. The engine and fuel delivery system on my truck and your truck are different but similar. My problem was a bad "lift pump" which was about $150 to fix, but caused a $1500 injector pump failure. I was nervous about pull starting my truck but it worked... the truck always cranked up after that.
