Hi, Im new and very confused about the car.
 

Hi,
Im new here and im not sure if this is the place I can ask questions. I was wondering, does the majority of Scion Frs make this annoying cricket sound? This is my 1st real "sport" car, and it sounds embarrassing to the point to drive my z4 instead if im going out with people. Is this lemon law-abled? I took it out to piercey toyota, where i brought the car on valentines day and they said that it was meant to be this way and there is no fix. When I got the car new it didn't have the sound, so i was wondering if theres anything i can do, or am i stuck with the sound? The car has 2500 miles on it. I'm very confused if this is a normal sound or not. This is also my 1st boxer engine so i have no idea what is normal and what isn't. please help :(

It's normal. It's the high pressure fuel pump.

If you are talking about the clicking that is the injectors and is perfectly normal.
If talking about the actual chirp from the fuel pump then that is normal as well and will come and go at will. You can try some different duels (may take more than one tank) or some people swear by different oils added to the fuel (I am not convinced but they seem to think it works).
There are about a dozen threads on the subject here if you dig around a bit.
It is not lemon law material if that is your only problem. Don't let a noise embarrass you.


Edit: I see you already posted this question in the Cricket thread. No need to ask in several places and the answers to all your questions are already there.

Welcome to .......The Forum, wolftec ........ :clap:

So, you have a Z4 ....... and you don't consider it a "sports car" ....... :iono:

Yep, the "crickets" as explained above, come free with most of these cars.

Try this, when your friends ask about the noise:

Yep, this little sucker has a very high compression engine that revs at very high RPMs, thus it takes two fuel injector systems to feed it. One of these systems is powered by a very high pressure, positive displacement fuel pump that directly injects the highest octane fuel into the combustion chambers. Thus, the sounds you hear is this high pressure system working to create 100 HP per liter of engine displacement. Yep, it's a screamer fer sure ....... :popcorn:

The crickets go away if you use E85 (with appropriate tune) Generally the higher the octane, the better it'll sound. If you only have crappy 91 you will hear more crickets. Try Shell V-Power?

You know what's funny, I hadn't had any crickets for the past 20k miles but my car is approaching 50k.

As other's said its normal sound.

Get exhaust, the crickets will still be there, but you won't hear them.

Thank you guys all for clearing things up, as I keep reading this forum, I guess my expectation for comfort were a little too high, as this is a very raw car.

E85 didn't kill off my crickets. Mine have mutated or something :iono:

Relatively inexpensive sports cars always have been "raw" ...... and they most likely always will be relatively "raw" ....... :)

Gloriously so.

Well we know where this is headed lol.

Anyways welcome to the forum Wolftec and enjoy your crickets. The standard script is more throttle and a twisty road ahead.

Do what we all do ...get an exhaust, it helps lol

I've been using Sunoco ultra (93), every single fill up for almost 30,000 miles and have never heard the noise once. My friend on the other hand does not consistently use the same gas and has chirping at only 5k miles or so. I'm not sure if it really matters that you use the same fuel every fill up but it could be the reason I've never had the problem (who knows), or I just got a good 86. Good luck
