Odd. I know of no speaker in the engine bay to make an audible alarm.

HPFP will periodically prime with truck sitting so maybe it's making the noise?

Are you sure it's coming from the engine bay and not inside the cab?

Strange I never heard that before, it sounds high pitched. Sorry I can't be of any help.

I'd say it's crying for a damper but I think you already have one. :bandit:

You’re not in the witness protection plan are you…. Might want to have your local bomb dog have a sniff or maybe someone has put a tracker on it. I know this doesn’t help but I couldn’t resist. ?

Try it again, but with your key fob far away. It sounds like your truck is sensing that you are near and it is priming the fuel system, getting ready for a start. Mine makes a similar noise just before I use the remote start.

FOB was far away at the time.

Oh yeah damper is solid. Though this is the time of year that it starts screaming too!

Is it your truck or is the backup battery in your automatic garage door opener telling you it is low and needs replacing?

Seems much louder when I get under the truck. Also seems to have stopped after a couple of hours?
