Why wont my car start? 2000 Chevy Cavalier 2.2?

all i can say is WOW YOU ARE STUPID because the water pump was not working it was not circulating water therefore the engine would take a couple hours to cool when not running and only about 5 minutes to overheat to a stall more than likely you cracked the heads maybe even the engine block since you obviiously dont know anything let a mechanic take care of it and next time the belt comes off tow it.
