Important Chirping Pump Update... - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I'll follow up again with my service rep about this. I'm in the same boat as the OP. Toyota is realizing that this pump is STILL not working 100%. I'll be one of the first on the list for the next revision. It's not fun going to car shows with a box of crickets under your hood.

I had the SU003-05176 installed and crickets came back in 250 miles. It's no good. Both this pump and my pump from a year ago always chirped. I'm at 12.6k miles.

To help you guys on this one...no there is NO fourth pump. This will basically be the 3rd attempt to get it right. Hope we all see the new one soon.

Original pump being the 1st attempt

I understand the reason for the hpfp. My point is that if the engine only ran port injection, there would be no need for the hpfp. Other cars with hpfp's don't chirp so yes, it is a Toyota D4S thing. And just to be clear, I know D4S exists on other cars. I'm referring to the fact that it's a system designed by Toyota and obviously poorly designed for our cars. I have not heard chirping on an is350 or gs350, both have D4S systems.

Wait, since when has the oct 17 tsb been deemed a failure? Almost all good things about this one. I've gone over 4k on mine since getting it and not a chirp.

*moves hand*

This is the fuel pump you are looking for.

The problem seems to be totally random, which must make it very hard to determine the actual cause. I still think it's cavitation related to water content.

Maybe I rev too high but I never hear "chirps" only the clicky type normal DI sound at idle. I have a first US shipment car.

I never went in for service because there no permanant fix. I will wait and see...hate going to stealership

samisons · 12-05-2013, 12:21 PM

Hopefully I get the new one as I was ordered one two weeks ago otherwise I should wait and see. It's only a minor annoyance.

My chirps are highly affected by ambient tempurature. When its hot out, once i reach operating tempurature the chirps are constantly happening at idle. When its could out, the chirps come and go

Mine are consistent no matter what the temps. Once the engine is all warmed up, they manifest.

I'm on the original pump and won't replace it until there is a confirmed fix with more than a few months of use and a couple thousand miles under it's belt.
