Busta..., I recently posted a problem starting my '03 as result of an oil change. I went from Rotella CI-4 plus syn 5/40w to Delo CJ-4 15/40w which is recommended for towing. Never had an issue with the truck starting even down to 17°F without plugging in the block heater. After the oil change, the truck had a lot of trouble turning over on nights when the temp is below 40°. Had to start plugging in the block heater every night, no problems with startups. I don't know if its related to your problem, just a thought. Good luck.

are you running a tuner or any other mods? how many miles you got on your truck. Im thinking there is a test to see if the glow plugs are getting weak or some might not be working, but I cant really tell you for sure. My plugs are getting weak I think too and im going to be changing them out with the new injectors soon. if I remember right the glow plugs are pretty cheep and won't cost a whole lot if you can do it yourself.
6.0 might be on to something too if you run a little long on the oil and filter changes. If you run alittle long on the changes that could give you the hard starting too.
