Common Troubles of the Fuel System
The fuel system is composed of several parts that allow gas to get from where it is stored in the gas tank to the combustion chamber where it explodes with a mixture of air in order to create the power that moves your vehicle. Fuel system trouble can appear in many different forms and be attributed to one of several different parts. Depending on the symptoms your vehicle is having you may be able to diagnose the problem. However, some of the signs of trouble between the parts are very similar and it will likely take the expertise of a professional auto mechanic to inform you what the trouble is. Let's take a look at the three of the most common problematic parts of the fuel system and the signs they may provide that something is amiss.
Bad Fuel Pump
The fuel pump is located inside the gas tank and its sole responsibility is, as the name suggests, pumping fuel. It is tasked with getting gasoline from the tank to the injectors. If the fuel pump begins to give out there is a good chance you will first experience a loss of power during acceleration. Other signs of trouble include a power surge, which is characterized by the sensation that you hit the gas pedal hard, without actually doing so. At freeway speeds a failing fuel pump may cause your car to jerk back and forth, seemingly dying and coming back to life. In the end a faulty fuel pump will no longer be able to provide the engine with gas and your car will not start.
Clogged Fuel Filter
Between the fuel pump and the injectors lies the fuel filter. It is designed to remove impurities and water from gasoline in order to provide pure fuel to the vehicle for optimal running conditions. If the fuel filter becomes clogged with contaminants it will restrict the flow of gasoline and eventually it will no longer be able to provide fuel to the engine, resulting in a car that can't start. Before it gets to that point you will likely experience a rough idle, characterized by drastic rises and falls of your vehicle's RPMs. Fuel filters are relatively inexpensive and can be replaced by a technician in a short amount of time.
If one or more of the engine's fuel injectors can not properly pump gasoline into the combustion chamber it will cause your vehicle to run very rough. This is because not all of the cylinders will be able to fire, causing missing, a rough idle and your car may eventually come untimed due to this issue. More often than not this problem can be resolved by cleaning the injectors, however they may need to be replaced if they've failed mechanically.
Fuel delivery issues are almost always first characterized by a harsh idle, and that should be your first clue as to what the trouble is.
