not getting fire!! need help

[short chevy]

going down the road in my 81 chevy at 55 mph it just died. it was runing fine no miss. i check ever thing and its not getting fire. put a new coil a new module anew rotor a new cap. I check to see if the wire that runs in to the distbutor was hot and it was. so i bought a used distbutor still nothing, and yes the rotor turns it not the cam or timing. is there some kind of ground that im missing? fire goes in the distbutor but nothing comes out of my new plugwires . can any body help
