Well if your fuel pump is bad it wont make any noise. Usually when you turn your ignition on you will hear like a whirring noise if its working correctly it will be coming from in or near your fuel tank. To see if it is the fuel pump take a rubber mallet and strike your fuel tank in the middle firmly; not as to puncture it ; while someone else trys to turn the engine over if this is the case replace it as soon as possible you dont want to do this more than a few times. Hope that helps
