How To Test Fuel Injectors with Basic Hand Tools HD | Testing Fuel Injection

Is your vehicle missing? Not running on all cylinders? A faulty fuel injector(s) may be the culprit. Today we show how to test the power source (harness connector) leading to the fuel injector and testing the injector itself while the vehicle is off and while the vehicle is running. Of course, check the specs for your specific vehicle. You can often find specs by searching via Google Images, Web or car forums for your specific vehicle. This was performed on a 1997 Nissan Maxima. Please check with your vehicle's repair manual for testing parameters. The fuel injector is a small, precise solenoid valve. When the ECM supplies a ground to the injector circuit, the coil in the injector is energized. The energized coil pulls the needle valve back and allows fuel to flow through the injector into the intake manifold. The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the injector remains open. The ECM controls the injection pulse duration based on engine fuel needs. ► Subscribe:    / carsntoys   ►► Tools and Supplies: https://www.amazon.com/shop/carsntoys ►► Multi-Meter: https://amzn.to/2KOdFZD ►►► Our most helpful videos (One million + playlist):    • 1 Million Views Playlist   Note: Any attempt to repair automotive parts and/or systems carries risk of personal injury.
