I tried to start my car this morning and it took a little more encouragement than usual how ever it ran, for about 15 seconds before cutting out and stalling. My fuel pump made a louder then usual hum and when trying to start it again made no noise whatsoever ever. I left it for a couple of hours and came back to find it starts, wants to stall when giving no throttle and cuts out when giving it throttle and the fuel pump seems a lot louder now. Is this the fuel pump dying or is it something else?
