It sounds like the fuel system is not primeing up are you turning the key on and waiting 15 seconds or so before you ty to start it? Recylcleing the key one time makes me suspect your not giveing it enough time to fully refill and pressureise the fuel system.

You really need it scanned with a real scanner, monitoring live data by someone who knows the 6.0 to tell for shure what is going on during crank.

alright boys and girls i said for the heck of it id replace both fuel filters to hope that may be the problem(since i just bought the truck and have no idea when they were replaced) they looked pretty new and the pump was flowing good amount of fuel through the bowl. a guy i know who runs a shop only working on 6.0 said its most likely glow plugs. i dont get it even when its hot out and warmed up it still once in a while doesnt start first time? and yes i wait long enough with the key on to prime the system.

That guys an idiot lol. If I were you I wouldn't be taking my truck to him to have it fixed. Have you checked your batteries with a load test or tested the voltage? Have you checked the FICM voltage? Alternators too? You need to spend the money and either take it to the dealer and have them run diagnostics on it to find out what the problem is or buy a monitoring system such as a dashboss if you have an iPhone or edge insight cs/cts to monitor the different parameters on this truck to better diagnose the problem. Sorry if I'm sounding blunt but it is what it is and you need to get it taken care of before it causes more problems and ends up costing you more money. Monitoring these trucks is the key to a happy ownership of a 6.0 good luck let us know what you came up with.
