Have you checked the fuses?

As previously mentioned check the fuses and look for restrictions. A plugged fuel filter could be a restriction or even a bad ground to the pump. Check to see if your geting voltage to the pump and what voltage are you getiing? If you know your getting proper voltage and you clean your contacts and sure enough you know there isn't any restrictions in the fuel line Is there gas in the tank? On most electric fuel pumps if your hearing is okay one should hear an audible ticking when enerized. If you can't hear over the starter cranking just turn the key on and wait for a minute or two for it to prime the pump. Check under vehicle for leaks or signs of disconnect were one might be losing prime and sucking only air. If its in the fuel tank pump was it replaced as an assembly or what?If it failed what caused it to fail? was it time for failure? how many miles or was it because there was so much debris in the tank the protective sock on the pickup tube has become clogged. Usually, electric auto parts are not returnable due to incorrect installation and so on. Not trying to be ignorant if its an external frame mount try running a seperate wire directly to the battery and see what you get? Good Luck...
