the alternator is out
Cause a no start situation.
Yes
A dead cell in your battery would do that . When you open the hood does your underhood light come on ? or if you have the key in the ignition and the drivers door open do you hear the chime ? if not it could be a poor battery cable connection or a dead battery
bad starter or bad connection to starter or bad ground on battery or starter
poor battery cable connection
bad battery or loose battery cable
Take it to an experinced mechanic and do not pass go!
Forgot to connect ground cable? Shorted Fusable link battery + cable not connected
I hope you did not remove a battery post while the engine was running (don't do it)? If so, it may cause damage to your alternator, and it will short out your ignition in the engine (engine stops). If there is no damage, it should work after reconnecting the battery posts. If you didn't do the above situation, I would check for a loose connection on the terminal or a corroded/broken cable. I hope you did not remove a cable from the positive or negative battery posts while the engine was running (don't do it)?

You left the light or something on last night and ran out the battery or your battery died
The alternator is bad. The engine is running off of the battery and when you take the cable off it has no electrical power. If the alternator was working, the car would keep running. Be advised, doing this can damage a healthy alternator. This is not a good way to test the system.
Have you removed the battery cables and cleaned the battery posts and cable connections? This is a frequent cause for the problem that you describe.
