A fuel pump relay is an electrical device that supplies power to the fuel pump. It is typically located in the engine compartment and is responsible for turning the fuel pump on and off. A faulty fuel pump relay can cause the fuel pump to stop working, which can lead to engine problems. That’s why it’s important to know how to check a fuel pump relay.
There are a few different ways to check a fuel pump relay. One way is to use a multimeter to test the voltage at the relay terminals. Another way is to listen for the clicking sound of the relay when it is turned on. If you do not hear a clicking sound, the relay may be faulty.
