    I heard a strange noise under the truck today. The truck had been parked for several hours in the driveway outside. Pretty sure that the pump was running on the E-Vap Canister. What say you "TW" ? Normal? Change in weather causing gasses to expand inside the fuel tank?

    I just thought it was kinda weird? The pump ran for 2 or 3 minutes.

    Normal, it runs a test after shut down for a few hours to check for leaks. All part of the evap system controls
