starting issue on a 89

ok so lately ive been having problems with my jeep, it would take a little longer to start up, now it wont even start, and i know its not the starter or any of the ignition wires or spark plugs. whenever i try to start it up it just clicks. does anyone know what might be the problem?

Try checking the Battery cables and the stater cables . . . possible loose wire? Give the starter a tap with something. Hope that helps

yea i checked the cables and tapped the solenoid and motor a few times
still nothing
