Ok one of my friends has a 2001 dodge cummins. He said the other day he got in it to crank it up, it started like usual and then started runing real rough. Then it got even worse and just cut off and will not start back. He has checked the fuel presure both before and after the filter and it was fine. I am not a dodge person as you can see by my sig but I am always willing to help out a fellow diesel gurru. Any help or suggestions would be great.

Any codes? Try cycling the key on/off three times and on the 3rd try (on) a message will pop up checking for codes? See what, if any codes pop up.

I don't know, I will tell him to do that tomm and see what happens and I will let you know!
