Engine idle chirping (cricket) noise poll.

[guybo]

I had a crickets a few weeks ago with Wawa gas.... no crickets until this past week when I filled up at an off brand station (I needed gas badly and it was right next to the on ramp for the highway) and they are back, but they sound a little different than before. Must be a different species of cricket?

Finally heard some chirping after 52,000 kms! I've tried many different gas stations from Ultramar (shhh) to Shell. Never tried fuel below 91, often filled with Esso 93, more so than before i've been going to the same Petro for 94, AND after regularly filling there i've gotten a chirp! However I would like to add that depending on the position of my clutch the sound cuts. Most prominently noticed during idle of course

My fuel pump makes so much noise it sounds like hammering inside. The dealer said that they know it is bad but they won't replace it because it costs too much. Doesn't matter to them that I only have 12,000 miles and less than two years.
I called Scion and they referred me to Toyota, no luck there. They said the same thing. We know it is bad but refuse to fix it. They told me to trade the car in and get a new one. I might do that but it sure won't be a Toyota

Have you taken it to another dealership? That's BS that it "costs too much," because corporate pays them for warranty work. They're just lazy, and I would tell them as much.

Guys, you all know that it's the Gas pump that is making the chirping noise right?, it's like you are asking a tire that you just bought to not be so noisy when you drive on the street.
No dealer is factory is going to change it unless it represents a safety hazard.

Road noisy tires, aren't a hazard, they are just noisy because of a design flaw.

This is EXACTLY, the same issue with our stock gas pumps. They are fundamentally flawed in design so that they chirp when they are going at a specific flow rate when our cars are on.

So, the only way to get rid of it....is???

wink:wink:, if you don't want noisy tires.......YOU CHANGE THEM FOR DIFFERENT TIRES

hint:hint:, if you don't want a noisy gas pump....YOU CHANGE IT TOO, FOR A DIFFERENT BRAND MODEL PUMP!!

I had chirping for the first 900 miles of my car's life, and now I don't have any chirping in my car, and I never will again. You know why?, CUZ I CHANGED MY GAS PUMP, for an Ethanol compatible one.

Did I just make this 300+ pages thread irrelevant or what? :-P

Not really. I don't want to spend money to replace something for such a dumb reason. It won't improve fuel pump performance or last any longer than the stock pump will, it'll just get rid of a small noise that I can only hear when I'm sitting in idle (so not very often).

Spending my money for their defect makes no sense.

Make, model and supplier of the FUEL pump may make the tread irrelevant. Otherwise this is just another "I fixed it" post of the several thousand that already exist.

Link to this pump? Seriously, you'd be the first to link a replacement high pressure fuel pump to my knowledge.

You likely replaced the fuel pump in the gas tank, not the high pressure fuel pump in the engine bay that makes the noise.

People running E85 typically report reduced noise anyway. I believe you made two changes and attributed the result to the wrong change.

I'm really sick of this chirping. How can I get rid of?

fuel formulation


we get very little problems with chirping here as almost all of our premium fuel (98ron) is ethanol free.


We used to have 100 ron which was 98 ron with 10% ethanol and yep car chirped.


back to 98 ethanol free no chirps, but it does take a tank or two to go away completely.


very occasionally on really hot days you will get the odd squeak.




strangely on E85, no chirps after a tank or two.


maybe is some additive in your fuel for cold climates or their sneaking in 5-10% ethanol in fuels supposed to be ethanol free

Cute.

Attached is a picture of your setup.

fortunately, the E-Force supercharger removes the pesky covers on the left and right.

Oh NO! What's that there on the right?

Yes, that thing, hiding under the A/C hose!

Surely not the OEM Denso High pressure GDI pump?

Oh... Damn... It is.

Always wondered if any of the old Bosch single piston demand controlled units would fit... Or the MM units that the Ecoboost fellas use... I thought, for a second, someone might have tried it. Then I realized.

Silly rabbit.

Your electric in-tank low pressure pump and the engine-driven HPFP are different things, grasshopper.

LOL Cole did not use the proper sarcasm font. He is well aware that it is the ethanol content that feeds the crickets. We have several ethanol free fuels here at different octane and I can pretty much makes the chirp come or go at will just by filling up at certain stations during hot weather.

Like others have already mentioned--you know there are two fuel pumps, right? The noisy one is the HPFP in the engine bay. You changed the in-tank fuel pump. Your lack of crickets is unrelated to your new in-tank fuel pump.
