Could my fuel pump be going?
Could my fuel pump be going? Hello.
I've been hearing a high pitch, RPM-related whine from my car. Noise appears to be coming from the rear. Cannot hear it from the outside. Quiet after cold start, louder after driving for a while. If I go to the back of the car, noise seems to be coming from the rear speakers, Nothing from the fronts. Does not matter whether radio is on or off. Still same volume - High pitch frequency. I also just purchased one of those cigarette lighter ipod thingies that transmits an FM frequency to the radio. You can't even hear it. The whine which I think may be my fuel pump is also coming through that, but in all 4 speakers when it's on. I don't think it's a failed rectifier bridge on my alternator since it only comes out of the rear speakers reguardless of when the radio is on(unless the ipod is hooked up). But something is whining in relation to rpm's. And something, possibly the same problem is causing an RFI interference when my ipod radio thing is hooked up. I appreciate any inputs. Thanks guys.

Turn everything in your car off. Turn the key to the ON position.
The fuel pump should prime for about 5 seconds. If it is the same noise, then it is probably your fuel pump.
Or if your feeling ballsy pull your fuel pump fuse while the car is idling. The car will stay running for about 5 seconds (oddly enough) and you can see if the noise went away.
