The bulkhead connector is a common area for your type of problem. Disconnect the battery first! Separate it very carefully so you don't break one of the tabs. Look for corrosion on any of the connectors, clean with sandpaper. But, the entire engine wire harness may be part of your problem and could resurface in the future. You could have a break in the power feed wire that runs between the starter, alternator and horn relay. How do I know you ask? I just replaced my entire engine bay wire harness because of a no start event.

The large red wire on the connector closest to centerline of car, just below master cylinder, wiggle it a little and see if you get power back. If so, as said above remove plug and clean and tighten connector. Sometimes it's just corrosion on the pin.
