You may find that turning the key may power on the accessories, and may even crank the engine. If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition. In some instances of a faulty relay, the vehicle will be able to restart once the relay cools off, only to stall out once again after the relay overheats.Ĭar not starting: Another symptom of a faulty ignition relay is a no power condition. This will cause the vehicle to immediately stall due to fuel and spark being cut off. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.
#DODGE SYMPTOMS OF LOW VOLTAGE RAM PRESSURE FUEL DRIVER#
Usually a bad or failing ignition relay will produce a few symptoms that can notify the driver of a potential issue.Ĭar suddenly stalls while operating: One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. When the relay fails or has an issue, it can cause major problems with the operation of the vehicle. When the key is turned to the on position, the relay is switched on and power is directed to the vehicle’s ignition and fuel system components, notably the fuel pump and ignition coils. It is usually located in the fuse and relay panel beneath the bonnet, and is responsible for providing power to the vehicle’s ignition system, and some of the fuel system’s components. The ignition relay is one of the most important electronic relays found on modern vehicles. Contemporary vehicles are essentially electronic objects and the quality of its service in all its four main systemic compartments (power-train, body, chassis and communication protocol), like that of any electronic contraption, is dependent on its electrical fixtures: cables, relays, etc. The electrical architecture of a modern automobile is its lifeline.
