if adequate charge is in your battery and fuses aren't blown the reasons why your fuel pump may not be working could be old wires are unprotected and earthing, wires are disconnected or most probably a relay is needed to boost the charge to the pump itself. Of course the pump could also be old and damaged. check with a circuit light to see if charge is being lost at any point from the ignition switch onward or check the mechanism isn't worn or dirty at the key switch internally. the problem could be many things, start at the most obvious.
