Just to the right of the distributor on the firewall there's a connector in a harness that runs down to the starter. All the power for the car runs thru it. The fuse links are in that harness- it's called "starter extension harness" in the vendors catalogs. Could be that connector is dirty or partially unplugged. I'd start there.

You can also check your power from the fusible links at this connector.
Here is a pic of the connector location(this is a 6 wire).
