Crack your fuel line before the fuel goes into the carb. crank it while inspecting the fuel line, fuel should pour out. If fuel doesn't come out check your fuel pump.

check relays/fuses first then the pump if you know how to test it
the pump is easy to test locate any fuel line unplug it tell a friend to make a quick one key turn if squirts fuel then pump is fine
but check the pump relay first to make sure and to begin with simplest
it seems you can tell it is the pump but you don`t know where to start

you probably have air in the lines, if you have a carb, spray some quick start into the carb and turn it over, if it starts and then dies when the starting fluid has run out, you probably need a fuel pump, since the running of the car should have blown out any air that was in the line, If your car is fuel injected, loosen the bolt cap at the end of the injector line that supplies the fuel,, and tap the key once,, ( don't start it,, ) just turn the key on and off 3 or 4 times, this should blow fuel out of that loose bolt head, if it does your getting fuel, if not, back to the fuel pump, also you can check this link, http://www.aa1car.com/library/us1296.htm
