2003 LB7. When truck sits over night is the only time I have noticed this problem. Truck fires right up as it should. Idles for about two seconds then dies, and won't start after that. The fix for this problem is to prime the fuel filter. After filter is primed truck starts and runs perfect.

Sounds like your filter housing could use a rebuild. Or maybe invest an AD II instead!

The rebuild kit is like 30 bucks or so and is a DIY, takes about 30 mins. It's just a few o-rings
