    My truck when it is cold or hot it turns over about 5 or 6 times before it will start. Does anybody else truck do this I even tried given it some gas before starting and still doesn't help.

    Same here, my 88 turns over 5-6 times before it starts.

    mine starts with 3 or so cranks, but when the winter temps drop below -10 then it takes few extra turns and slugish half idle start.

    Do you give it 2 seconds after turning the key to the "run" (not start) position?

    The fuel lines have to pressurize if it's been sitting (and probably very much temp dependent) so you have to wait for the fuel pump to pressurize the system if you want quick starts.
