firebird wont start

My son drove the firebird up town,, and went in the store,, when he came back out the car wouldnt start,, i tried to jump start it nothing,, put the battery off my truck and put it on the car,, but it still wouldnt start.

Check the wires going to the starter. If they are lose the car won't start. If the starter is going bad try hitting it with a hammer while someone turns the key.
