Warning: When checking the injection start pressure, take measures to protect your hands from the high-pressure fuel jet, which can cause serious injury.
Attach the injector to a device with a pressure gauge to check the injection pressure. Using the pump handle of the device, create fuel pressure and check the injection start value.
If the test result is not within the limits specified above, replace the injector.
