This diesel injector cap block off tool is a [must have] tool for everyone working on common rail fuel pipe. When the pressure of the common rail is too low to start the engine, one of the possible reasons is a defective diesel injector returning excess diesel back to the tank. To identify the individual defective cylinder, you can remove the diesel injection line from the cylinder, and use this diesel injector block off tool instead of diesel injection line to seal common rail system. If the engine can be started normally, and the common rail pressure return to normal value, it's to say that the injector of this cylinder is malfunction. And more, if your scanner cannot perform certain tests, this diesel injector block off tool can also be used for identifying engine knocking sounds that could possibly be caused by a single cylinder issue.
