getting 12 volts at the battery (red) wire on distributor w/ key on?  As i mentioned earlier, if you get voltage to the distributor (red wire), but not out of the distributor (no spark) could be pick up coil, ignition coil, or module.

if no power to the distributor with key on, perhaps ignition switch, or wiring.

Also are you testing for a spark or seeing if she will start up?
