Question about 2002 Chevrolet Malibu
Fuel pressure, (41 to 47 psi).If the pressure is good then the pump is ok. If the pressure drops off fast after turning off the key then you have a bad pump or fuel pressure regulator. With bad mpg I would think a bad regulator. You can do a quick check on the regulator by removing the vacuum hose and looking for signs of gas in the hose. thanks.
