91 2500 NOT CRANKING

2012 GMC C2500

I cranked this truck 2 wks ago on the first turn over and now it turns over but doesn't fire. I replaced the ignition module and spark plugs. All wires are intact but still not cranking. My rotor cap prongs were caroded but cleened them off. Any ideas?

Disconnect the coil wire at the distributor, ground it and crank engine over-do you have spark. If so replace the Cap and Rotor it has to make it out of there to the plugs. If not do below.

Test for power at the coil positive terminal and also the resistances of the pick-up coil in the distributor.
