2005 Honda Odyssey car won't start

I've had 3 starters put in -after the 3rd one working for two weeks, then suddenly the car won't start again- not even a clicking sound- then after trying 30 times it started but there was a weird sound like whistling or something underlying the normal engine sounds-not like a bad fan belt- then we turned it off for fear of wrecking the engine so I turned it off and took the key out and the engine kept on running but making clunky sounds , until if finally stopped...

we tried it again and the same thing-horrible, awful noise-

Fuel pump, computer, or ignition switch...any ideas - should I tow this to the dealer??? HELLLLLLP
