fuel pump?? Sign In
my 97 gmc makes ahigh pitched buzz,which eminates from about midship , is it the fuel pump? Other (possibly unrelated) symptoms are uphill hesitation when the engine is yet cold , and a ticking noise coming from under the hood on the passemger side. almost feels as though it wants to downshift from overdrive at about 50mph.
