RE: Distributor timing
Rotate your crankshaft clockwise until the line on the damper is lined up with the TDC mark on the cover. Now make sure #1 cylinder is at top dead center, "both valves closed". The distributor has a little notch in it that is there to align it tothe camshaft position sensor. The tip of the rotor should be pointing to this mark. That is also the #1 cylinder location on the distributor cap. On some distributors, you can put a 3/16" pin to hold the rotor in that position. "We used to use a 16 penny nail bent over". On the newer set up's, you have to use the DRB scan tool to verify the correct rotational position. I know in school, a lot of us reinstalled the distributors 180 degrees out until we got used to putting them in. If someone would show you who knew how, you would see how easy it really is to install one. On your 5.9, the distributor shaft runs the oil pump also. You have to make sure the input on the pump lines up with the bottom of the distributor. A proffesional mechanic should be able to install a distributor in 15 minutes. If you can get the truck to one, maybe it would be worth the couple bucks to let one try.
