Have a 2001 2500HD with the 8.1. Bought it as a project. It wasnt running so i replaced the fuel pump and it went to running fine. i let it sit over the winter and fired it up the other day and had a bad skip to it. A few weeks later it wont hardly run at all. When it does start it will idle rough and wont take the gas. I just changed out the fuel filter. ( looked like jelly inside). Could it be the fuel pump again?
