Today and on another occasion, while standing outside with the car idling, I noticed a high-pitched humming/whining noise coming from the back of the car near the rear tires.

It went away after a couple of minutes but I was wondering if anyone knows what it is. The car doesn't seem to have any problems.

 

hmmmm some sound happening with my bro's rsx. Although he went to the dealership to get it checked out, he could not induce the sound but on the way home it kept doing it.

 

Do you have an aftermarket fuel pump? Sounds like that to me...

 

I do have the Walbro fuel pump upgrade but is it audible from outside the car?

 

yeah, thats the fuel pump..... no worries

 

is it intank or inline? i had a inline sitting in my trunk.... in my old car.... its all i could hear haha

 

just going to say fuel pump no worries...

 

So it's normal for it to sometimes make more noise than at other times because, like I mentioned, the noise stopped after a couple of minutes?
