How do I find the fuel pump relay

look in owners manual,it will show you which one it is in the fuse box under the hood!it's also marked on the fuse box cover where the location/position is!!there is a fuse also.when you turn the switch to on,not start,do you hear the fuel pump prime(humm)FOR 2 SECONDS,THEN GO OFF.IT DOES THAT EVERY TIME YOU TURN KEY TO RUN!if it don't prime,it ain't starting.
