Question about 2005 Chrysler 300
A small but important part of your car's engine fuel delivery assembly, the fuel pump relay is an electrical component that controls the pump. Also known as a relay switch, this car part turns your fuel pump on and off when you start your vehicle and shut it off. Everytime you turn on your ignition, the relay switch lets the electrical current flow to the fuel pump. Once both the pump and your engine are running smoothly, the fuel pump relay automatically shuts off. The fuel pump will then be controlled by the oil pressure unit. In case your pump relay stops working, it's the oil pressure switch that will serve as a back-up power relay for the pump. Because the fuel pump relay is switched on everytime you turn on your ignition, you should hear a distinct sound (it could be like a whistling kettle or a blackboard being scraped) whenever you start your car. If you don't hear that distinct sound and your engine takes longer to crank up, you may have a problem with the relay switch. Fortunately, finding a compatible replacement relay for your vehicle is just a few clicks away at Auto Parts Warehouse. When you buy from our site, you can enjoy our free shipping services, low-price guarantee, and flexible payment options.
