Part 3 Injector Balance Test

Injector Balance Test Procedure (Part 3 Of 3):

Test Procedure And Examples:

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. Fuel pressure should be within specified range. If not. refer to CHART A-7 for fuel system diagnosis. Related Tests, Information and Procedures
3. Fuel pressure should hold steady. If not, refer to CHART A-7 for fuel system diagnosis.
4. 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.

NOTICE:
Fuel pressure range is 284-325 kPa (41-47 psi).
