I have a 1986 Jeep Comanche 2.5l 5spd it was last tagged in 2000 so 22 years parked untouched, I’ve finally got around to messing with it, I put a good battery in it and hit the key and nothing happened at all no lights or anything nothing worked so I jumped the starter and it turns but doesn’t engage and honestly I'm a novice at electrical and don’t know where to start.
