8.1L HARD STARTING

2003 GMC Sierra

Engine Performance problem
2003 GMC Sierra V8 Two Wheel Drive Automatic 10000 miles

my 2003 GMC sierra with 8.1L gas has 9800 miles on it and It is hard to start sometimes. It sometimes take a long time to start while it cranking for a long time. First start of the day it starts up fine after all night of rest. Some times after I run it and park it and come back in an hour it takes an extended period of cranking time to start. I changed the plugs. This truck did not see much use over 7 yrs. After it starts it runs smooth with power and no hesitation and drives great down the highway etc etc. I already changed the plugs because they looked old a little carbon build up and dirty
