Ignition Problems

Hey everyone...I'm stumped and could use some advice. Have an 84 CJ7 258/4spd that won't start. It turns over but will not fire. When I turn the key to the 'off' position, it fires (one time) like it is going to start. Here are the parts I have replaced: Plugs, wires, coil, distributor pickup assembly, cap, rotor, ignition switch, battery, and ignition control module. All voltage readings/resistance reading seem to be what they should be according to the Haynes repair manual, it's getting gas, but I'm not an expert. PLEASE HELP...beyond frustrated.

did you replace the ignition switch on the column where all the wires plug in or the key switch that moves the ignition switch?

Did it just start this on it's own, or did you change the small wires at the solenoid?

Sounds like the run circuit is switched with the start circuit.

Are you getting voltage at the coil?

Did you check for spark at the plugs while cranking?
