Just got this little darlin and have a couple questions. When the ignition key is turned on the fuel pump buzzes withou stopping sometimes. Car always starts. Would this be the pump or the relay? The part in the front passenger corner (fuel distributor?) that attaches to the turbo has an electrical plugin that I am leaving unplugged because it buzzes loudly if plugged in, whether the car is started or not. What is this and why is it buzzing? I have 2 other volvos but they aren't turbos and aren't set up like this one at all. As you can tell, I'm a novice but love working on these cars. The turbo is oil cooled, and doesn't seem to boost. Bob
