1989 Chevy Caprice I think I killed it.

Engine Mechanical problem
1989 Chevy Caprice V8 Two Wheel Drive Automatic

I have a caprice classic brougham and when I turn the key I get nothing. Nothing at all without listening to the very best of ability. I think the starter gives out a little 'micro click' and a little plunger pump thing under the hood gives off a "nanoclack"
At all the battery is fully charged, however I have had multiple problems with alternators. The starter also went out like 2 months ago which I replaced. I hope the engine is not locked up it had oil and some water. I drove it home parked it for about 2 hours. When I came back and turned the key I got nothing please help
