    From time to time I find my fuel pump running when parked in the grauge. Turning the key on then off stops it.
    What causes this? Is this problem normal?

    Thanks

    U have a second gen?
    2005-2015?

    If so, it's just the evap pump doing it's self check. It's normal and may happen multiple times a day.

    You probably just never heard it.
    It's doing it's self checks tho.

    After Approx 4hr depending on last drive, gas level, ambient temp, and prolly a dozen other parameters
