Can a bad fuel pump relay cause misfire

A bad fuel pump relay can cause misfire because the relay is responsible for supplying power to the fuel pump. A faulty fuel pump relay will not supply enough current to operate a properly working fuel pump.

The result will be a lack of pressure in the engine, which could result in a misfire. This is why it’s important to have your vehicle checked by a mechanic if you experience any symptoms of a misfire or other enginerelated issues.
