Why when I try to start my car does it not work and instead makes a loud noise. on 1994 Ford Explorer

It doesn't even seem to turn over. After a few tries of trying to start it, it just begins making a loud noise almost as if running. It continues until it seems as if it overheats. It has ran fine all day until now. It won't start at all just continues this. Did I blow my engine more than likely? I had coolant in. Oil was low but I added it to try again. Still no help. Idk what is wrong

An engine needs fuel and spark to run. Verify that engine has both of these and that fuel is getting into the engine. Any gas smell inside the air cleaner housing when cranking? if you have fuel and spark but no firing, then it could be a mechanical issue. If there is clunking sounds or other loud abnormal sounds that you don't normally hear, it could be a bad bearings, slipped timing chain, or yes; possible major engine damage, especially if it was ran without oil.
