The click is fairly loud and rapid

What you are hearing is the starter solenoid clicking. Normally when the starter is bad, the solenoid on the starter lets out a fairly loud click with each turn of the key.Just one click with each turn. The fact it is rapid click like ratcheting sound is more the symptom of low battery or bad connection at cable or terminal. I know you tried to jump start but it is possible the cables did not make good connection or the battery terminal themselves have bad connection, I would start by charging or jumping the battery again. While the jumpers are charging the battery, remove the terminals and be sure clean then reinstall them and be sure tight. Continue with jumpers and try cranking agin after jumpers have let your battey get a good charge. be sure the vehicle you are jumping with is running. If you know your battery accepted a good jumping, terminals are clean and tight,. you have a bad starter./ Ypou would be surprised that battery terminals a cn look 100?5 but just looseningand retighten makes the connection neeeded. it does not take much of a bad or weak connection to cause your problem
