another no start need help

91 XJ 4.0 man

Ok so I go to start the jeep today nothing at all not even a crank look for lose wires dont see any try again nothing. decide to just tow it home slam the hood in fustration try it again it starts right up. get it home samething tried slaming the hood again nothing. When you turn the key you can here a relay clicking. all fuses are good all grounds are connected hood slamming not working anymore. I've had this problem before hood slamming worked then, havent had any issues in a very long time.

What should I look for?

jump at the starter to see if that works, sounds like your ignition switch has a loose connection to me
