I have a 1999 Chevy K1500 that I have recently bought. I love the truck but the electric fuel pump makes a fairly loud whining sound when running. If you turn the key to the on position it will whine until the pressure is built up, then it stops making noise. As soon as it's started again the whining is back. I'm being told that this is normal for some Chevy truck models. Does this sound right? Anybody else have this issue?
Thanks Brian
