Don't know much about the Duramax diesel but this sounds like an air leak in the fuel supply system. When it finally does start does it blow white smoke for a short period of time and run just a little rough, if so that is a sure sign of air in the fuel. Found this out on an old 671 Jimmy diesel.

I have a similar problem. There is a cluster of metal lines near the fuel tank that has some rust holes in mine. I'm told the repair will cost ~$600, but it isn't my daily ride, so I haven't fixed it yet. Often, I will get out of the driveway and a few hundred yards down the road before it stalls, then I need to manually pump it back up. After that, it tends to be good for the day.

Your hand pump probably needs to be rebuilt! You can buy a kit with everything You need to do it for about $10.00 bucks!
