Diagnosing a leaking fuel injector involves several steps. Start by checking for a strong fuel odor around the vehicle and observing if there's smoke from the exhaust. Use a fuel pressure gauge to see if the pressure drops when the engine is off; a quick drop may indicate a leak. Inspect the injectors for visible leaks or fuel stains. Finally, you can use a noid light to test if the injector is receiving the right amount of electrical signal. If unsure, consult a professional.
