Fuel injectors How do I detect a bad fuel injector
Hi there, well if you have a bad fuel injector the easiest way to check is if you have a misfire code come up then pull the spark plug out and with the wire connected to the spark plug, place the plug on metal on the motor and turn the motor over( make sure your wearing gloves when you do this, i wouldnt want you to get shocked) and if the spark plugs are firing then you narrowed it down to a fuel problem. next you can take an ohm meter or light tester and backprobe the pigtail while they are still conected to the injectors to make sure they have power and if they do you really narrowed it down to the injector being faulty or cloged
