When I try to start my ranger it just makes a clicking sound and doesn't turnover .. Battery is good so I want to know what it could be ?

Yes sounds really close to drivers side fender

get a helper to try and start it,while you look/listen under the hood.most likely the starter relay solenoid is bad,IF the battery is good/fully charged,and all connections are clean and tight. the big red wire from the battery goes to one side of it,then the other side (red wire)goes to the starter.also a small switch wire on it too. google part number F492,see what it looks like. reply back with findings.
