Odd noise in IS
I have searched and cant find exactly what im looking for. My car (02 IS300) has this weird... whine? Its not really a whine, i dont know how to explain it. To me it sounds like a fuel pump thats about to go out. Its at idel, driving slow, WOT, all the time. Its not the fuel pump though because I turned the ignition on and I can hear the fuel pump come on but doesnt make the noise. I need a accessory belt desperately and Im wondering if the belt could be making the noise. Maybe the pulley? Anythoughts?

Things to check:
-Drive belt tensioner pulley bearing (tip of driver to bracket)
-Alternator internal regulator can buzz when it's going out (tip to housing)
-Power steering pump (tip to housing)
-water pump (tip to housing)
Just poke around a little bit. Let us know what you find!

if it sounds a lot like the fuel pump it could also be your radio. sounds dumb i know but ive heard a high pitch whining noise come from radios almost not noticeable if your not listening for it. Sounds like the fuel pump but quieter and higher pitched. Any updates?
