Remove the spark plug wire or disconnect the coil pack or remove the coil pack that goes to that cylinder.Place the stethoscope or rubber hose against the injector and listen at the other end to hear if the injector clicks If a Noid light or ohm meter is not available a stethoscope or a piece of rubber hose can be used to to listen if the injector click.Confirm with an ohm meter that the injector has the proper resistance.(Noid lights are inexpensive and available from most auto-parts houses) With an ohm meter check that there is power to the injector connector or use a Noid light.Inspect the terminals of injector connector to make sure it is not corroded.Remove the connector from the injector on the cylinder that is not warm.If the engine is hot then drop droplets of water on the exhaust manifold or wet your hands and if possible quick touch the manifolds. If possible quick each of the exhaust manifolds with your bare hands and find the one that’s not warm.Start the engine when cold and let it run at idle for 5 – 10 seconds.

One, multiple or all the cylinders are not firing.ĭiagnosing dead or clogged fuel injectors is difficult because it acts the same than a bad coil, dead spark plug, broken spark plug wires and or electrical problem.Clogged fuel injectors, unlike dirty injectors which reduce fuel flow, prevent fuel from flowing through them.
