It is the hottest day of the year, and although your Honda Accord's engine attempts to turn over, the car will not start and you are late for an appointment. The most common cause of this problem is a defective Honda main relay, but fortunately this is not a difficult part to replace. The Honda Accord main relay is responsible for sending commands to your vehicle's fuel pump as well as powering the fuel injectors. A faulty relay will stop your car from running, especially during the hottest months of the year or after running the vehicle for a long period of time. In some cases, it is necessary to replace the fuel pump and the Honda main relay at the same time. Regardless of the specific diagnostics, have a mechanic determine that the relay is the culprit. On Civics, Accords, and other Hondas, the relay typically requires replacement after eight to ten years. Since the relay changes from one model year to the next, check for parts compatibility first.
