well, this is kinda a mess. let me think out loud here.
so when you turn the key on, but not try to start it, you should hear the low hum, and that would be the fuel pump priming the system....thats normal.
the clicking you are hearing is probably the start solenoid clicking back and forth (normal if the battery is weak on amperage)
if the hum you sometimes hear is higher pitched and fast, that would be the starter spinning, but if its not starting, then that means the bendix is not engaging the flywheel.
so at this point, i wonder if you starter bendix is either damaged or not being thrown out to the flywheel. do you have a pretty good idea what i mean by that?
