Issue with ignition system

culprits would be a blown fuse, bad ign. switch or bad connection @ the firewall plug.

Good info except there is no fuse anywhere in the ignition/ start circuit, except the main fuse link

might be the pickup in the dist, sounds like you've replaced everything else.......

Make sure ECU is well grounded, and make up a good heavy clip lead. Jumper directly from the coil + terminal to the battery and see if it starts

Have you checked for spark right at the coil?
