The function of the vehicle fuel system is to store and supply fuel to the engine. The engine intake system is where the fuel is mixed with air, atomized, and vaporized. Then it can be compressed in the engine cylinder and ignited to produce energy or power. Although fuel systems vary from engine to engine, all systems are the same in that they must supply fuel to the combustion chamber and control the amount of fuel supplied in relation to the amount of air. If you're having trouble starting your car, a fuel pump may be the problem. At Nexar Auto Repair in Houston, near Katy, TX, we offer fuel pump pressure diagnostic test and replacement, complete fuel system diagnostic and repair, fuel filter replacement, fuel lines leak check, fuel pump relay, and much more. Our certified mechanics are experts in diagnosing and repairing all types of fuel systems and other auto mechanical issues. We can help you get your car running like new again. If your car won't start, the first thing you should do is check the fuel pump. If it's a relatively new car, the fuel pump may just need to be replaced. In older cars, the fuel pump may be worn out and need to be replaced. If the fuel pump is not the problem, we may be able to diagnose and repair the fuel system.
