I just noticed that when i turn my key to the position where just my dash lights, radio and compressor come on i hear a loud buzzing/humming that goes away in about 20 seconds that was not there before. It drives and starts normally but i was just wondering if my starter was going out or if i needed to get it seen? has anybody else had this problem its a 1990 lincolin towncar 5.0 v8. thanks

    Could be the electric fuel pump making the noise. They all do to some extent.

    Have you ruled out the air pump for the rear air shocks?

    i know its not the air pump, i know its failing though.. but the pump makes more of a growling noise. I am going to buy some springs from autozone and change them my self, because when i turn the car off i can hear all the air leaving the bags. But yeah its not the pump and its coming from the engine compartment. so i guess it isn't the fuel pump?
