Ultimate Guide to Diagnosing and Troubleshooting a Faulty Fuel Relay


Ultimate Guide to Diagnosing and Troubleshooting a Faulty Fuel Relay

A fuel relay is an electrical device that supplies power to the fuel pump. It is typically located in the engine compartment and is activated when the ignition key is turned to the “on” position. If the fuel relay fails, the fuel pump will not receive power and the engine will not start.

There are several benefits to checking the fuel relay regularly. First, it can help to prevent the engine from starting if the relay is malfunctioning. Second, it can help to identify potential problems with the fuel system before they become more serious. Third, it is a relatively simple and inexpensive procedure that can be performed by most do-it-yourselfers.
