Vehicle wants to start when releasing the key

I replaced the ballast resistor and that didn't work. Replaced the ignition module and that didn't work. Gapped the distributor to .008 and that didn't work. Threw in a known good working coil from my Duster and that didn't work. Also replaced the rotor because it was looking a little beat up. Can't get the thing to fire up at all.

Under the dash at the ignition switch connector I have 12.5v going to the ignition switch with the key off and when the key is cranking I have 8.5v going out on the ignition start wire. Does that mean I have a bad ignition switch?
