The Fuel System in a vehicle is not just one thing. It has a number of parts with many function. And, it’s goal, is getting fuel from the fuel tank to the engine.
Some of the components included are the fuel tank, fuel pump, fuel filter, fuel injector or carburetor.
The Engine Control Unit (ECU) controls the air/fuel mixture and other fuel system operations. And, is based on inputs from a Mass Air Flow (MAF) Sensor, a Throttle Position Sensor (TPS), and an Oxygen (O2) Sensor.
But, to make the Fuel System work as it should, all the parts must work together and function as a team. So, if any one part fails to work properly or is out of adjustment, it can throw the whole system off.
