Spends too much time on here
Not sure how often it happens but I caught it three times now. It happens just a few minutes after a long drive with the ignition off. Sounds to me like it’s at the rear of the truck and likely the fuel pump. Pretty loud and lasts for only a few seconds. Not sure if it goes thru some type of purge cycle or if it’s even normal. Never heard this on any other RAM I owned before. Seems odd since I have no mechanical issues or electronic alerts. Anybody else experience this?
