Something everybody overlooks......

The Ignition Module

Not sure about that year, but on an '83 its on the firewall left of the master cylinder, viewed from the front.

Do not try to disconnect it with a screwdriver, as Evil as this sounds, grab the wires firmly, on either side of the connector, and pull STRAIGHT APART.

Verify the color on the body, where the wires enter, it should be BLUE---Always replace with the same.

Take it to AUTOZONE or ADVANCE AUTO to be tested for FREE!........They do not see this one often, so it will take awhile, for them to hook it up!

INSIST on 5-7 tests, one after the other (warms it up)

If it fails, and you need a New one, TEST IT, BEFORE YOU LEAVE THE STORE!!!!!...............Don't even ask me why!!!!

If you need anything else, respond at THIS POST, I will be alerted.
