The water pump is driven off the cam belt and is hidden behind the timing belt covers,if the cam belt is off and you tried to start it won't as the timing will be wrong,if you mean the serpentine belt that's different.
You need air (which unless there is a serious blockage you will have),fuel and a spark for an engine to fire so check for these 1st.
If there is damage to the front of the engine check the distributor caps as these may have been damaged and wiring in the damaged area.
