i have a96 k1500 4-wheeled drive pick-up. it starts hard first thing in the morning or if it sits for along time. it normally starts with second spin of the motor but lately it takes at least a dozen times or more once warn up it will start on the second spin. it has a 5.0 motor with a automatic tranny, have no clue as what to do. once runing it runs fine, it did stall twice, but i pull over and it starts right up and runs great, been dealing with this for over a month.
