"Crickets" - is this true?

To answer your earlier question, no this is not my first direct-injection car, nor am I "inexperienced" when it comes to direct injection. My last 2 cars before my BRZ were BMW 335i sedans, an '07 and then an '08, and both had noticeable "ticking" coming from the engine compartment at all times, which I came to learn was the high-pressure direct-injection fuel pump. It never bothered me because it was better-insulated (as you mentioned) and because it was more of an innate unobtrusive "ticking" rather than an obnoxious and noticeable "squealing" like in the BRZ.

I also say I am experienced in GDI because I sell cars for Kia, which almost exclusively uses GDI in their new vehicles, so I need to be able to understand and explain the technology to prospective clients, and the Kia vehicles also have somewhat of a prominent noise from the GDI. Nothing like the twins though, which is what surprises me; you can put a quiet, insulated GDI pump on a $14,000 Rio, but can't put one in a more-expensive, performance-oriented vehicle like the BRZ/FRS? Doesn't make sense.

Yes you are right my old Golf GTI had this ticking sound too from the Hitachi HPFP (Made in Japan ironically), and the crickets only happen when I first crank the engine and I really have to listen for it with the hood opened, otherwise I can never hear it ever after driving it for any reasonable distance.

I take it the GDI with Kia/Hyundai is from Mitsubishi? I think Mitsubishi have had this technology since the 90's?

The twins is a really cheaply built car, I think they spent the bulk of the budget on the chassis, leaving everything else much to be desired. I basically just went from one rubbish car, to another potentially rubbish car taking my chances with a different make lol!

Yeah, I've had all 3 revisions of the fuel pump at this point and always use Shell 93 Octane. ChirpChirpChirp

[BRZZZZZZZZZZ]

I have crickets with both Shell 91 and Husky/Mohawk 94.

I once ran an E91 320i without the engine cover on. My god it was a heavy beast and removal made a mk 1 Fiat Punto sound refined

Are you really calling it rubbish because of a chirping noise that has zero negative performance/reliability effects?

Yes it makes noise, no it isn't hurting anything at all.

I've ran V-Power since the first time I put fuel in the car.


Last week I went on a 1500km road trip in the states. By the end of the first tank with ethanol gas I had crickets. Come home and put Shell and I'm as good as new!

No crickets since day 1. She only drinks Chevron 94.

[pushrod]

I've had crickets since the morning after I brought the car home. Gets me laid.

I manage the a scion dealership, I just last week got out of the company lease and purchased my own 2014 frs as a demo and had about 8k on it. I have the sounds that come and go.
You will notice some gases/weather will make it worst or come back. They have a new updated pump that my dealership will happily put in for me but I am going to wait until the fix is fixed for good. I simply turn up my music or listen to the exhaust some more.
I know as a owner the sound is annoying, but every time I rip threw a corner I could care less how the car sound.
I hope you get better service from your dealership, the advisor for sure could have done a better job explaining it to you

It's something that happens to a lot of vehicles with HPFPs. Everyone will tell you they have a fix, but nothing works for everyone. Just like how some types of hard drives are louder clickers, it's just one of the noises it makes. Doesn't indicate a problem and it sucks but its life.

No crickets and I only use Esso.

No I meant overall build quality.

OK so this is only the 1000th thread on this subject!
I have tried to use nothing but Esso non ethanol from the same high volume station since I got the car and was cricket free for MOST of the time.
The one time I got too low on fuel for comfort (about 3 weeks ago) I stopped at a small neighborhood Pioneer station and got half a tank. Wasn't half an hour later it sounded like late summer at dusk under my hood. My car was also running like CRAP so I figured more than just the ethanol was up. I burned through that tank and went back to my regular fuel. Silence (well other then all the other weird and wonderful noises that the boxer makes)!
I was going past the same station about a week later and stopped in to talk to the attendant. Once I convinced him that I wasn't trying to get anything out of hem and asked about how much premium gas they sold he responded "not much". We took a look at the records and that gas had been in the station tank since MAY! The fill up before that had been November of 13.
So... the moral of my story is that ethanol is certainly a factor (in my OPINION based on MY experience) and always try to get your gas from a station that uses lots of premium or you could be getting stuff that is well on the stale side.

Other than the first tank (which I think was from Pioneer), every other tank has been ethanol free and I have not heard crickets. There are quite a few options: Shell 91, Esso 91, Canadian Tire 91, and Costco 91. Pretty much any gas that is higher than 91 has ethanol in it. I also find that I tend to get better gas mileage than those on the 93, but, not as much performance. Seems contradictory, but, meh, I don't have crickets.
