Might want to check the dis cap and rotor as well. Where you going to find a computer for it? 1981 is different from the 83 model year...

Irs not the Coil. I installed a new one with the same results. Glad I did not can the old one, cause its the factory Mopar part from 81. Where is this Spark control unit? Does it happen to be drivers side engine compartment under a plastic shield?

Yes, I tested the spark on number one spark plug. Dead as a door knob. I have not changed the Dist Pick-up. I even pulled the timing belt cover off to see if it may have snapped. Its gotta be something stupid....LOL...I am sure I will be kicking myself once it running again...LOL

Ok, I have it Sparking now. I messed with elecrical connections and a couple had slight corrossion. I messed with the gear selector while turning it over as well, still will not start. I am wondering if the throttle body is not shot, or varnished up from years of not being run. Any other ideas?

It's not a throttle body, it's a carburetor. Try pouring a little (Tablespoon or so) gas down the carb and see if it tries to start.
