Q: Fuel injector not working

asked by on

One of my fuel injectors is not functioning properly, and the car also misfires.

A: The fuel injectors on the engine get power ...

The fuel injectors on the engine get power at all times from a common source, and the ground side is through the engine computer. The injector may be bad, or the engine computer’s internal injector driver burned-out and the computer needs to be replaced. I recommend having a mechanic, like one from YourMechanic, discover which component has failed by determining the source and cause of your misfiring engine.
