'97 Firebird - Fuel Pump Issue!
I have a 97 Pontiac Firebird Formula. Overall it runs very well, however, when the outside temperature exceeds 90 degrees, my fuel pump starts humming after an hour or so of driving. It never makes a sound during cooler temperature days with the equal amount of drive time.
My question to anyone that can help is: Should I just go ahead and replace the fuel pump, or is there something else I should be addressing?
Help will be greatly appreciated.
