When do you need to replace a fuel injector?
As you connect each injector, the pulse intensity should remain the same. It shouldn’t change until you connect a faulty injector that creates too much resistance for the pulse to travel through easily. When the pulsing light dims as you connect one of the injectors, that injector is faulty and needs to be replaced.
How are fuel injectors connected to one another?
The electrical pulse is transmitted through each of the injectors to one another, so one faulty injector could cause issues in multiple injectors. Disconnect the wiring clips to each injector and begin the test again. With none of the injectors connected, the flickering pulse should transmit through all of the wires without any issue.
