1991 240sx-starter will not work

Ok maybe the battery maybe wrong as in not enough voltage amperage to kick it over. Or maybe what happend to me is somehow between my battery dying and the car shutting off somehow the starter got stuck. Try putting it in another gear and role it a bit. If not pull the starter which is not that hard and try to start it while its off the motor. Caution thats a last resort option. Be careful please ive done it but be careful with the connection and the starter itself when trying to spin it. Dont know ur situation but i would check the battery and all the connection and see if the terminal are correct.
