If the relay is not being powered, trace the circuit backward to the power source using the factory wiring diagram. You will find the interruption, or the faulty control module, if applicable, using that strategy. A similar procedure has to be followed if the starter continues to function after you release the key. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an electrical circuit/component diagnostic and the responding certified mechanic will get this resolved for you promptly.
