I came home last night at about 9:30 pm and parked the car in the garage. This morning at 7:30 am I went into the garage and heard a buzzing sound coming from near the rear wheels of the car. My best guess was the fuel pump was still running (I had had a different problem with a fuel pump not running when the ignition was turned on with a 2000 Jaguar about a year ago). I turned the ignition on and off without cranking the engine, the buzzing continued. I started the 4runner, ran it for about 20 seconds, and shut the engine off. Buzzing stopped.
