How to Solve the Issue of 4 Fuel Injectors Shorting to Ground?
1 Answers
Carefully check whether the fuel injector has low resistance causing a short circuit or low loop voltage. The fuel injector has two pins, one is the power supply pin. Turn the ignition key to the ON position to supply power. The other pin is the ground control, managed by the engine control unit (ECU) to determine the injection timing, i.e., the duration of grounding.
