Fuel System Repair
The fuel system’s sole purpose is to get fuel from point A to point B – the gas tank to the engine. Without a properly performing fuel system, your car won’t be going anywhere. Let’s look at each part of the system, how it functions, and indications of it breaking down.
Fuel Pump – The fuel pump draws highly pressurized fuel from the gas tank and delivers it to the fuel injectors or carburetor, depending on the age of the vehicle. A broken fuel pump will result in noise, the vehicle acting like it is out of gas, or it won’t start at all. Typically, a broken fuel pump will not set off the check engine light. Auto Doctors recommends replacing the fuel filter, which will maintain a healthy fuel pump, ever 15,000 miles.
Fuel Injectors – The fuel injector is an electronically controlled valve that can open and close several times per second, allowing the right amount of fuel into the engine. The injectors should be cleaned every 25,000 to 30,000 miles to ensure proper flow of fuel.
Fuel Pressure Regulator – The fuel pressure regulator maintains the proper pressure in the injector’s fuel inlet. It should be replaced when a pressure test indicates there is a problem.
Any problems with the fuel system should be seen by a professional immediately. Along with the ability to repair each component of the fuel system, Auto Doctors also uses a chemical flush that cleans the entire system more efficiently than any over-the-counter fuel cleaner.
Also, you may want to consider preventative maintenance with Auto Doctors, to prevent any part of your fuel system of breaking down.
