Hissing noise in Camry 2004

Hi, I have searched thru the forum and it seems that my problem has never been discussed before. Ok, the noise seems like coming from the area under the instrument panel and near the gas pedal. Its off when I put the key in ACC and on when at ON position. The more I accelerate, the louder it is. The noise seems linked to the gas as even when the engine is off and I hit the gas, the noise varies accordingly. Any idea would be appreciated.

the only system in the car that i can think of, that is on when the engine is off, (key set to ignition position i'm guessing?) is the fuel pump. so perhaps it is related to the fuel system - how, i have no idea.



Jack the car up if appropriate, (use jack stands always) and have someone else work the gas pedal while you try to trace the source of the hissing. Not likely it's anything inside the passenger compartment, so its got to be an engine electrical component(fuel system or possibly even brake system) or maybe even transmission related.

Thanks for the input. This problem happens after I install the window module to roll up the windows automatically. Is it possible that I might shorted something? And for some reason, I dont know if related to the noise or not, my FR speaker dies too.

to follow up with my situation, today I have a chance to pull some fuses out to isolate the problem. The result are fuse 8 and 17 can shut the noise off. You maybe right AlmightyCamry777 . What do you think? Should I replace the fuel pump? Is there anything else in the fuel system could cause this noise?
