Fuel Pump not working??

hi all, yesterday my friend jacked up my car and replaced my fuel filter and now the car will only crank, no start. When i initially turn the car to "on", i don't hear the fuel pump whirring anymore....could it be like a relay or fuse or something or maybe the connection messed up when the fuel filter was replaced??

i tried searching to see how to figure out if your fuel pump isn't working and i think someone said to turn the car to on and then relieve the fuel pressure on the end of the fuel rail and if fuel comes out then its not the fuel pump right? please help, sarah
