It sounds like the motor is locked up. I would suggest starting with checking the oil and see if there is anything in there and if you see any metal in it when you drain it.

Then we need to put a socket on the crank pulley nut (#3 below) and try to turn the motor over by hand. You can actually do this first if you want to but if you cannot spin the motor by hand then it is locked up and needs to be replaced. I am pretty sure this is what you are going to find based on what you stated.
Let us know what you find with this. Thanks
