Hi there. If the engine code is showing that you’re experiencing a fuel injector misfire, it’s most likely not related to the fuel pump. Most of the time, this is a fuel injector sensor or connection malfunction that triggers this type of error code; or causes the engine to actually misfire in the first place. I’d inspect all connections and sensors first before heading to the fuel pump; or contact one of our local experts to complete a Check Engine Light inspection; so they can help you diagnose the issue.
