Have you ever thought of your car's ignition key as a magical sort of device? In a way, it is. Once you insert and turn it in the ignition, it triggers a series of processes that brings life to your vehicle. If you've ever wondered how fuel reaches the engine as soon as you crank your motor, that crucial task is performed by a small but remarkable device: the fuel pump relay. This relay is like one of the hands of the engine control module in your vehicle. Once you turn the ignition key and crank your engine, the ECM automatically engages the relay so that it can turn the fuel pump on. The process is actually simple. All that the relay does is deliver power to the pump during this initial process. Once the pump has come to life and the engine is in full gear, the fuel pump relay disappears in the picture. It only appears again when you turn the engine off-to disengage the pump. So simple a task, yet this is very important to the proper operation of your vehicle. In fact, you can't afford to have the fuel pump relay fail, or your car may not start at all. Don't worry when this happens, though, because Car Stuff can help you when you find the need to replace your vehicle's stock relay.
