I have replaced the fuel pressure regulator, the coolant temperature sending unit, the coolant temperature sensor, fuel pump relay, and the check engine light still comes on and the code is 157 indicating low voltage regarding the mass air flow sensor. I have not yet replaced the mass air flow sensor. My fuel gauge reads empty all the time so I suspect the float in the fuel pump/sender has filled up with gas as these brass floats do over time.
When the check engine light comes on, the vehicle stumbles terribly as though the fuel pump is not delivering fuel to the injectors. I have not replaced the fuel vapor canister yet but I don't think that's what's wrong.
Anyone have any ideas as to what my problem is?
