Yes thats right.....it will sound like a humming/buzzing or vibrating sound....if u have trouble hear it u may need to have someone turn the key while you listen from the back seat or under the fuel tank

You have a fuse / relay box under your hood. My 2002 L100 special edition, 4 cylinder, is located near the battery. You have a relay and a fuse in series. A fuel pump operations check, section 4-3 of the Haynes Saturn L-series 2000 to 2004 manual, you can hear a soft whirring sound for 1 to 2 seconds when you turn the ignition to the ON position. I can confirm mine makes this sound when I do this. Good luck with the fix.
Note, I had a crack in my fuel pump, but I took it to an ex-Saturn dealer 4 or 5 years ago because I did not want to mess with it at the time. They had the part and fixed it in 4 hours, but it also cost me $1000 to replace the fuel pump and install a new fuel filter.
If it turns over when you turn the ignition key and you have power. Check too see if it is getting gas. The fuel pump could not have enough pressure to start the engine. When you first turn you key on listen and see if you hear the pump runs for a couple of seconds. If no sound probably fuel pump. Do a pressure test first.
It could be a clogged fuel filter or a bad fuel pump. To check if its the fuel pump, get some starting fluid, remove the air intake and squirt some down in the intake. You'll need a helper for this one. Have him try to start it while you spray. If it starts and runs only for a moment your fuel pump is bad.
THE ELECTRIC FUEL PUMP IN THIS CAR IS IN THE GAS TANK AND IT IS COOLED BY THE FUEL IT RUNS IN, WHEN U RUN OUT OF GAS YOU SEVERLY OVERHEAT THE PUMP AND THEY SEIZE UP, WHICH IS WHAT HAS HAPPENED TO YOUR PUMP, U WILL NEED TO REMOVE THE GAS TANK AND REPLACE THE ELECTRIC FUEL PUMP.
if you have no fuel pressure check the fuse n the underhood fuse block even if its good its still most likely the fuel pump is bad the fuse rarely blows even when the pump is bad,,the 6 cylinder only produces fuel pressure when cranking the enigne
