There is no test for module in distributor, but they often cause this kind of problem. Also while in there, check the pickup coil wires to make sure they are intact.

try the oil pressure switch, that was a common problem on Gm trucks when I used to work on them, the oils switch was bad and woulden't allow it to start and the ones I worked on were on the back of the distributor.

ok number 1 piston should be a top dead centre & mabe on the top of the cap is a mark or number
if not then there should be a mark on the lip of the dizzy!
if not then just choose one near the front & set the points at that point on the point of sparking! [ready to open points] make sure you have spark or you may have left ou the insulator on the points locating pin!!!
then its a matter of the firing order!
i hope this helps
cheers Rob

You didn't specify which size engine you had, so I have included both engine firing orders of your model year...
