sounds like a new motor is in order, if the motor is locked like you think. when you tried to crank it did the starter just go click and buzz? if so don't try to crank or you will overheat the starter and ruin it.
is there any oil in the engine? how many miles on this car?it looks like it is an interferance engine so if you broke a cam belt you bent the valves which would lock it up. sorry I am not 100percent sure on this engine.

If the motor is seized, which sounds like it is, overheating the starter is the least of his/her worries.

nor does it have pushrods...or a timing belt. it uses chains...
have someone verify that it is indeed locked up...then go from there with your options.

So, putting a couple posts together from others: Could it be most likely the rattling was loose chain jumping teeth and then bent valves due to interference engine?

haveing never been inside one of these i just assumed from the little i read about it that it used a belt. Still sounds like a locked motor.

most seized engines have bottom end failures rather than top end. perhaps the oil pump or pump drive failed followed by the lash compensators rattling then the crank seizing in a bearing(s)

25 years ago, my dad, who never had a good habit of checking engine fluids or parts, ran out of oil in his Mazda and it picked on the top half of his engine, in his case, and not enough oil made it up to the overhead cam bearings and the cam welded itself to the bearings, or another terminology - he 'spun the bearings'. I rebuilt it out in the driveway, and it lasted many more thousands of miles, and thereafter he checked his fluids on a more regular basis.
