Starting Issues

Yeah,your ignition solenoid is probably stuck.The solenoid is that black round cylinder looking piece bolted to the inner fender next to the battery and has a mass of wires connected to it.Try tapping mildly on the side of the solenoid with something hard like a screwdriver or hammer.Do this several times then reconnect the battery.If this fails to work then try once again.Your best bet would be to replace it.They are only about $7 - $10.Doesn't matter where you get them,it will always be the same brand.No one else makes them (I think summit may have a HD one).And yes,they are quite notorious for sticking like that.Especially if the car sits a lot.

Something else you could do to help prevent this.Upgrade your starter to a high torque mini starter.These are the ones they used on the later 91-93 foxes.They draw much less current and are much lighter than that MASS that's currently in there.They are also quieter.
