Q: Fuel injecter

asked by on

If I have a fuel injecter circuit open how can I find which one it is?

Hi Danny. A professional mechanic would start by downloading all OBD-II trouble codes, as this would lead them to a bank (or side of the motor) where the faulty injector is faulty. They would then inspect each one till they find the trouble source. One ’very easy’ way to test each injector is the method described in this video.
