    Has anyone had an issue with their fuel pump continuing to run after stopping and turning off the ignition? I noticed a humming coming from under the back of my truck and believe it was the fuel pump; not sure if it's located inside the tank or outside. I was able to get it to turn off by hitting the lock/unlock button on my key fob a couple of times. FYI- 2017 Pro.

    Normal, it’s performing some sort of evap test or something.
    I believe It’s in the manual

    It’s part of the evap system, it the fuel pump.
