2005 6.0 just quit starting

[mec111990]

i have a 2005 f350 6.0 the past week the truck started taking longer to start it would crank for about 10 to 15 seconds then it would fire up sluggishly. i turned my tuner back to stock and it went away then i turned my tuner back up and the truck was running fine starting normally then today went out this morning truck started right up went to the store and came back out and it cranked and cranked then slowly started building up and fired right up drove it to my next stop and shut it off and it wouldnt start upat all just crank and crank i've checked the battery both good charge checked the ficm 48 volts and 48.6 when cranking tried changing out the cam shaft position sensor but couldnt get the old one out at all not even with a pair of pliers. the truck isnt throwing any codes at all for anything i've had issues with injectors before got them all replaced but now im at a complete loss as to what is wrong i dont know where to locate the icp sensor or how to even get to it i knnow its on the back of the motor behind the turbo anyone have any clues as to what it could be im out of town till thursday for work so if anyone can give suggestions and talk this up i would appreciate it like to get as many suggestions as possible and ill start tryign them thursday night

If you go to a shop that has the right diagnostic tool yes. I'd find one that has the tool so you don't end up spending tons of money.

That's my only problem though to get it to a shop I have to toe it an that's gonna cost me money then it's gonna sit at the shop and thatll cost me money to

Could be a hpop or a blown o ring on one of your dumby plugs.
