Using a Multimeter to Test Fuel Injector Resistance Ohms. Learn how to check fuel injectors to make sure they are working. You use a multimeter on the resistance settings and measure the ohms of the injector. All injectors should be within .5 ohms of each other. If an injector is out of the resistance specification, that injector is bad. Symptoms of bad injectors are a check engine light with codes P0300 through P0308, misfiring, hesitation, poor fuel economy, stalling, and a poor idle.
