click...click...click... DAMMIT!

Not clear to me if you

A....Hold the key and get "one" click each time you twist the key to start or

B....Hold the key and get a "string" of clickey, buzzy, noise

If A, bad starter relay or bad solenoid, or maybe bad battery connection right at "big" starter terminal

If B, bad battery, bad cable or dirty / loose terminal or connection.

"Learn" to do roadside troubleshooting

"Learn" to jumper the starter relay AND the starter

To do that make sure the car is safely in park / neutral, and jumper across the starter relay two largest, exposed terminals. This should cause the engine to crank.

If it a "buzzes" or gives a continuous clickety--clickety, bad battery, cables, terminals

If you get one click, reach down and wiggle the big battery cable at the starter and try again.

If no joy, jumper across the two starter terminals. Again, should crank. If not, you need to get out the wrenches.

Sometimes banging on a starter will shake things loose in an emergency, that is "no" fix.
