After 2 track days, particularly the recent one in 115 degree heat last Sunday, the chirping has gotten really loud even right from start up. This is after having the pump replaced once. I just might go back to dealer for another.... Ridiculously loud chirping.

So far it looks like a coin flip if the new pump will fix the issue or not. I'm staying put waiting until there's a confirmed fix

Because numerous people have indicated they used nothing but 93 and they have chirps.

got mine fixed 100 miles later still ok

that's funny cuz I go with 93 but what are we supposed to put in it then

Well, just about everyone who has used ethanol-free gas has reported the crickets go away. Since I also don't care about the chirp until they actually produce a chirp-free pump, I'll either continue to not care about the chirp or kill it with e-free gas.

Very, why would you question it? How is the jury still out when I have proven it is not case and others also concur?

Are you also saying all those on here who have had their pump replaced are lying that the chirping came back after replaced ?

or perhaps you have some insider knowledge, gas stations are misrepresenting their octane levels ?

I'm on my second pump. I have run nothing but 93 octane, and this pump chips too. Hasn't affected the driveability any.

I have 5 friends with the 86 and none of them have the chirp only I did and we all use 93 I asked them last night on one of our drift outtings

not going to affect ur driving just noise but u should get it fixed its only covered for 30k miles and its free otherwise 1500 out of pocket

if I am between the vin range and have the problem (chirping) will they fix it under tsb or warranty

The chirp is even happening on the 2013 production models which are really far outside the VIN range.

44 days and 1520 miles after the pump was replaced.
I heard the crickets this morning.
It's hardly noticeable now, but it probably is because it's only the first day of chirping. :(

"Green Dot" correct?

My service consultant wasn't helpful enough to find that out for me.
All I can say is that the parts were ordered on 2/22, receive at the very end of April, and installed on 5/22. It most likely is the green dot one.

took my car in for the the crickets a 1,050 miles, they gave me the run around about no official recall and that its not affecting the cars performance. then they called me a few days later wanting me to bring in the car to see if if the part toyota sent over had a date later than the one currently on the car. I brought it in, and they ended up replacing it.

no crickets for now.. ive only put about 150 miles on it since, so now im just playing the waiting game.

btw, i use shell v-power 93 octane.

Third tank no problems

Just finished a full tank (refueled at a quarter tank) of booze-free gas. Not one chirp. I'll ask this until someone answers: Has anyone taken apart a chirping pump just for GP?

I've had mine replaced twice. Recently went back to my dealership. Service tech called Toyota because apparently mine has been the only FR-S brought back after having it replaced the first time. Toyota sent "engineers" (told by my service tech) and they wanted to see what was going on. Pretty much said to replace again. Getting tired of going back. I'm starting to become a regular at my dealership. Sucks.

3190 miles and chirping is still going. Going into the dealership at 5k miles to get routine check up and I'm going to bring it up then.

I had my pump replaced probably 4k miles ago and the chirping is back. I'll see if I can't get another replacement the next time I take it in for service which should be another 800-1000 miles.

Had mine warrantied and 300 miles later its back

A little over 200 miles on the TSB fix and still no crickets for me.

500 miles on this pump, I only use Shell 92 and thankfully no crickets yet.

Crickets have made their return off and on. Had the 1st new PN pump fix at 5,000 miles. Now at 15K and still get crickets occasionally.

I know this is TOO early to write about, but I thought I would share this.....I check a few other blogs and people are reporting that 91 Octane Ethanol Free fuel stops the chirps. I tried it and wow, it worked. My engine has never been quieter. Seriously. I was at a quarter tank and filled it as this fuel is difficult to find, and within 20 km my chirps were gone. I know it is early, but hopefully this may a be solution.......hopefully....

It has been pretty well proven throughout this thread that ethanol-free gas fixes it. Problem is that most people do not have access to ethanol-free gas.

I really wish people would read. Octane HAS NOTHING TO DO WITH IT. It's the ethanol content in the gas causing a lubrication issue in the fuel pump producing the chirping noise. This has been confirmed over and over. I swapped between a Chevron and a Shell station with 93 octane and I've gotten less chirps from the Chevron station due to probably a lower ethanol content than the Shell station I went to.

There must be a fuel additive out there that would fix the crickets.

From what I have seen on this thread and others, 2-cycle engine oil can help, but is best avoided since it basically introduces crap into the engine that isn't supposed to be there. In general, fuel additives don't do much to help the car, and are mostly a waste of money.

For me, the best solution at this point is to just leave it be. A couple users have mentioned that once they get up there in miles (most >10k), the crickets simply disappear. Patience appears to be a virtue in this case :iono:

I'm pretty sure my dealership doesn't want to fix my crickets or anything else under warranty

They won't give me a loaner while they replace both of my condensating fishbowl taillights and "diagnose" the crickets, even though they say they won't know how long it will take.

I suppose they just want me to camp in the waiting room for a few days?

So, I've been told by two different people (one a good friend that loves to work on cars and knows a lot about them, the other a relative that owns an auto shop and does work on cars every day all day) that the crickets should be coming from the rear of my car, not the front, as the fuel pump should be located back there, not under the hood. The noise is quite clearly coming from under the hood and has gotten worse over time. Can anyone confirm the location of the fuel pump for this car? And why, if the pump is in the back, the noise comes from the front? Could it be the injectors instead?

No crickets for the next 3 days. I only heard it that morning. That day was more muggy than usual. Nice trade wind over the weekend and no crickets now.

Electric fuel pump is in the tank, high pressure mechanical fuel pump is under the hood.

Please take a service manual and/or diagrams with you when you talk to these two people and show them that the High Pressure Fuel Pump is located in the engine bay, on the driver's side. There is a pump by the tank, to my knowledge, but it is not the focus of the chrips.

Neither of these guys have ever worked on an FR-S, obviously.

Yea also known as the injector fuel pump. The normal fuel pump in the tank pushes the fuel the length of the car, the HPFP then gets it up to the pressure required for the injection system. If you have ever heard an old inductor or dewatering pump it basically makes that sounds just at a much higher frequency. they should just wrap it in dynomat lol

Mine chirps, don't care. When there is a fix, I'll get it fixed. Meantime, e-free gas.

Hmmmm. Has anyone tried acoustically insulating the pump? I wonder if a wrap or enclosure would cause the pump to over heat?

went to have mine repaired for a second time and they told me that Toyota is aware of the problem and they are working to fix it and not to repair mine.

I had the cricket for a while now and taking it in this Friday to get it replaced. The chirp seem to be getting louder so needless to say I've been listening closely for that noise lately. Tonight when I pulled into my garage I heard the chirping again, only this time it was much louder and a different interval. So I popped my hood for a closer listen, but figured out the sound was way too much on the passenger side to be the fuel pump. Only then did I realize it was a real cricket on my garage floor :bonk: Toyota could have picked a better animal sound for our engines to imitate...
