TO add, to be safe, pull the plugs before cranking as oil tends to find its way into the cylinders. If enough finds it way in you chance a hydro lock situation. Stand back from the plugs as oil will get everywhere. Once oil is out of the cylinders, put them back in, and attempt to fire.
Oh, battery better be 100% secured too. Best way to burn up a truck, fall on your side/top, arc out, and light up that oil/gas thats dripping from everywhere!
