    I've gone out to the garage at night just to check everything is good before going to bed. Two times now I hear the fuel pump running on the wife's 2019 4 runner. Seems like it should be off when key is turned off. Any ideas? Thanks

    Roughly about 6 hours after shutdown.

    Pump time ( the time you hear things) is usually a few min.

    Subject to change without notice... lol


    Like I said it’s a non issue and nothing you need to think about.
