When the starter wouldn't work, I'd hear no sound at all from it. I'd only hear the fuel pump.

A blow by blow account of my starter experience is on another forum:

I'm not willing to make the generality that most of the parts in this starter are inferior. When I took it apart, most parts looked fine. I'm trying to understand why the magnetic switch became corroded. (Is it supposed to resist water or is water never supposed to get in it?) If you have to change yours, I hope you will look inside the switch (it only involves removing 3 phillips head screws to see the part I photographed) and tell us if yours is corroded.
