First do the SIMPLE thing: check if the distributor is getting the low voltage supply! If it isn't, that's the whole problem. Next, see if the high voltage coil is getting its low voltage supply and then if it outputs the high systematic and save yourself money!

SOURCE: 89 s10 blazer no spark

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.

That could be correct, or 180 degrees off. Top dead center on the crank shaft can be on the intake or exhaust stroke.

I mixed the distributor cables up,so i need the order to correctly connect

If the wires are still in the distributer, AND, if you have a stock intake manifold, the firing order is on the manifold. If it's a V-8, the number 1, 3, 5, & 7 plugs are on the drivers side of the engine. The number 2, 4, 6, & 8 plugs are on the passenger side. The number 1 plug wire can be located by looking at the distributer from the front of the engine and visually looking between the distributer and the number 1 plug. Visualize the distributer as a clock. The number one position should be located between 4 and 5 o'clock and should have the longest wire of those on that side of the distributer.

If the wires have been pulled from the distributer, then, then, remove the rotor cap, turn the engine over slowly until the rotor is pointing to the number 1 plug. Using the firing order on the intake manifold, starting with number 1, replace the wires going clockwise around the distributer.

Remove cap. Remove number one spark plug. Turn key off...have friend manualy turn engine over until you feel air blow out of number one spark plug hole. when you feel this look at rotor in will be pointing close to number one. Set your wires on cap to coincide with that. Hope this helps:)
