Well i move back to pa and took my car to my buddies family dealership for the whine of the fuel pump. Within 3 days i had it fixed and was driving a normal sounding car again. Unlike the first time i went to the dealership i bought the car at never even brought up the fact that there was a recall on the fuel regulator. My buddy called Detroit and said this is not right. They informed him that there was a recall on the fuel regulator and to try that i have put on about 1500 miles and no problem. I must say that they took good care of me. Also if you are having this with your 2004 cavalier don't settle for the dealer telling you it is normal for the car to sound like it is goin to die cause the fuel pump is screaming.
