The fuel pressure may rise after the fuel injector stops pulsing. Record the fuel pressure value immediately after the fuel injector stops pulsing.
DO NOT record the higher fuel pressure value.
6. Energize the fuel injector by depressing the Pulse Injector button on the scan tool. This will energize the fuel injector and decrease the fuel
pressure. Record the fuel pressure indicated by the fuel pressure gage after the fuel injector has stopped pulsing. This is the 2nd pressure reading.
7. Press Enter to return to the Select Injector screen.
8. Add all of the individual pressure drop values in order to calculate the total pressure drop. Divide the total pressure drop by the number of fuel
injectors in order to calculate the average pressure drop. The difference between any individual pressure drop and the average pressure drop
should not be more than 20 kPa (3 psi).
If the difference between any individual pressure drop and the average pressure drop is more than 20 kPa (3 psi), replace the fuel injector.
