Chart C2-A:

Fuel Pressure Specifications:

FUEL PRESSURE RANGES 284-325 kPa (41-47 psi)


TEST DESCRIPTION
Numbers below refer to circled numbers on 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.
