What's That Normal Sound?

[JessV]

Hey everyone! 23,000+ miles and still going strong here! I ended up putting plasti-dip on my rims and she looks like a real race car now!

So my question that I have always been curious about since owning my '15 Mustang for little over a year now is regarding what is that two second noise you hear (that sounds like it is coming from underneath the car) when you press on the breaks before you push the start button?

It kind of has the high pitch sound of a high-end SUV or truck having those automatic step/nerf bars that retract underneath the vehicle before you get in?

Thank you Stangsters!

The sound you hear is fuel pump priming when you push the brake pedal before starting the engine.

Be sure to keep an accurate count of how many times it primes itself. When it gets to 5,000 the car explodes.

That was a joke, right..?

Yes. Sorry about that. Sometimes I just can't control this typing finger.

Great question and thanks for the answer!

At first I had no idea what you were talking about then I had to playback starting the car in my head to imagine that sound. I never thought about it but it is good to know.:clap2:

You even hear a whining sound from the throttle body too if you listen carefully.

Have you guys also noticed, when you start the car, it greets you with a sound. but sometimes the sound changes to a different tone?? I wonder whats the difference.

I have noticed it. Like sometime times the sound plays through the center speaker only, sometimes its all speakers.
