Injector Balance Test Procedure:

Fuel Pressure Range:

Chart Test Description: Number(s) below refer to circled number(s) on the diagnostic chart.
1. Engine cool down period (10 minutes) is necessary to avoid irregular fuel pressure readings due to "Hot Soak" fuel boiling.
2. Energize tester one time and record pressure drop at the lowest point (Disregard any slight pressure variations).
3. If the pressure drop of all injectors is within 10 kPa (1.5 psi) of the average fuel pressure drop, the injectors are flowing properly. The actual amount of pressure drop is calculated by subtracting the second pressure reading from the first pressure reading.
