I have heard the alternator does it,cold drains the battery too,if it's not started for awhile can kill it.
Your starter is incapable of being drained. It is an electric motor. However a bad starter can drain your battery
Yes, very, very, quickly. The Starter Motor has a very high operating current, that will drain even the heaviest duty battery, fairly quickly, if an engine fails to start.
bad starter, or wire to starter
No, a bad coil will not drain the battery.
bad starter or bad connection to starter or bad ground on battery or starter
Could be the battery is drained or bad. Could be battery connections at battery and or starter are dirty and or loose. Could be starter solenoid is bad. Could be starter is bad.
My suggestion is to make sure that you have a good connection between your starter and your battery. Is the starter even functioning? If not, it is probably a bad starter, a bad battery, a bad fusible link for the starter, a blown fuse, or just a bad connection.

If you have a starter that spins but doesn't engage the engine and a battery that is always dead then I would look closer at the starter then the regulator. The regulator is part of the charging system but if the rectifier is bad then it might be possible for the battery to drain flowing backwards through the charging system but highly unlikely although possible. As for it to stop the starter from engaging the engine, that is not possible.
The starter could be bad. Or the battery. The starter could be bad. Or the battery.
If the starter is bad no. Check battery, starter and solenoid to be sure which is bad.
dead battery bad starter solenoid bad starter loose or corroded battery or starter cables
Could be,low battery, loose or dirty battery connections, starter is bad, starter solenoid is bad, neutral safety switch bad or out of adjustment, starter relay is bad,
