truck wont start.. plz help!!!!!!!!!!!!!!

The other day on my way home my truck was acting like it was out of gas. The next moring i got to start it and it would not crank.. it would turn over but it would not crank. I changed the fuel pump , checked fuel pump fuses but when i turn key on the fuel pump does not hum like it did before..
and it still will not start. I sprayed starting fluid in the intake and tried to crank it and it still would not fire up.. ANy ideas..?

Could be the battery.

battery or fuel pump, check connections and pump.

Do you know if the spark plugs are firing?

Has a new fuel pump in it that didnot solve the problem
