If the pressure is OK:
-
Check the pressure regulator.
-
Proceed to: PRESSURE REGULATOR, INCREASE IN PRESSURE section below.
If the pressure is not OK:
-
Replace the pressure regulator.
Checking the Pressure Regulator, Increase in Pressure
^
Connect pressure tester P/N 9985496 and manometer P/N 9995230 to the pressure regulator.
^
Pump up the pressure in the regulator.
^
Check that system pressure rises as much as the increased pressure in the regulator.
300 kPa (43.5 psi) + overpressure = system pressure
^
Disconnect the hose from the pressure tester.
System pressure should return to 300 kPa (43.5 psi).
If the pressure regulator is OK:
-
Check the residual pressure.
If the pressure regulator is not OK:
-
Replace the pressure regulator.
Checking Residual Pressure
^
Switch ignition OFF.
^
Disconnect jumper lead between relay base terminals 1 and 3.
^
Reinstall fuel pump relay.
System pressure must not fall below 200 kPa (29 psi) in less than 20 minutes.
If pressure is correct:
-
Proceed to: DISCONNECTION OF PRESSURE GAUGE section below.
If pressure is incorrect:
-
Fault may be due to leakage from injectors, connections, fuel pump non-return valve or lines.
-
Repair as required.
