When was the last time you changed the fuel filter?

You might try draining the WIF using the valve on it and then try priming the filter.

x2, thats a very real possibility. Hard starting is a symptom of bad injectors. Do you get any white haze out of the exhaust at idle? Have you checked your oil to see if there's any diesel in it? You might still be under the injector warranty.

If it just cranks, try primer pump on fuel filter housing. If it starts right up you may either have a bad filter or the filter housing is defective. (Help me guys I forget what it's called). Can be bought rebuilt, and is a common problem on the LB7. May be headed for one myself. When my truck sits for a long time, won't start unless I use the primer pump. Replacing the filter helped, but after awhile acts up again.
