I have a 2001 dodge 2500 with the cummings turbo diesel. I am useing 50 50. I broke down today thought i ran out of fuel put more fuel in truck will not start. I cant hear the lift pump in tank so i dropped tank put new pump in tank and i still dont here it come on. The truck still wont start. I replaced fuel filter and there was no fuel in bowl so i added fuel and tryed to start ran for 30 seconds and shut down. There is a spot for a pressure gauge when i push in the shrader valve air comes out. I had tryed starting it so much killed the batterys hooked up jumpers and.cranked on it more. I even put gas on a rag and put over intake it would start up and run for 15 or so seconds and shut off i did it that way a bunch. I still have air in the lines just like the lift pump is not coming on. I checked fuses and solenoid all is good. So what are your ideas on how to fix the truck. Also there is four wires going to lift pump and sending unit i dont no what ones go to the pump to check for power.
Sorry forgot first time useing phone for this.

Sounds like your lift pump is not getting power. If I remember right from my brother's 2001 the lift pump should run non-stop when you turn on the key until it generates some set amount of pressure.
You need to check for power, with the 4 wires, the 2 biggest (thickest) ones will be to power the pump; the sending unit will be low power lines and will be smaller.
If its not getting power and there isn't a physical wiring break somewhere, then maybe whatever pressure switch tells it to stop is stuck open?
The wires are all the same size.
The lift pump need to be working or the VP44 will die and need to be replaced as well as the lift pump. Disconnect the fuel line and make sure it is pumping out of the lift pump. This is a serious problem with that truck. These come into the shop where I was working and the boss would have to tell customers that the lift pump died and took out the injector pump.

If the injector pump failed why cant i get the air out of the fuel lines. Thats why i think something is going on with lift pump. Truck will start and run for 30 seconds after i let it sit for 2 hours. I have not worked on it busy working at job site. Maby tonight.
Maddasher you was right worked on it some more tonight and its the injector pump i ordered a new one. Thanks
