BASIC INSPECTION : Special Repair Requirement (TEST 6: Major Leak in Fuel Injec-
tors/Fuel Injectors Open)

INFOID:0000000001162520

NOTE:
• CONDITIONS PRIOR TO TEST
- The entire low pressure system must be in good condition.
- Check the sealing of the high pressure pipes and unions.
- Test 3 High pressure supply pump (pressure control valve) check is OK
- Test 4 High pressure supply pump (volumetric control valve) check is OK
- Test 5 Rail high pressure regulation circuit check is OK.
• CAUSE
- Not enough or no rail pressure during starting.
- The engine does not start.

CHECK INTERNAL FUEL TRANSFER PUMP

1.

Turn ignition switch OFF.

2.

Disconnect the return system connections at the fuel injectors and close off the return pipes so they are
leak-tight.

3.

To authorise a 15 second cranking engine and carry out this test it is essential to carry out the following
procedure:

-

Disconnect high pressure supply pump (volumetric control valve) harness connector

-

Turn ignition switch ON.

-

Perform “SAVE DATA FOR CPU REPLC” in WORK SUPPORT mode with CONSULT-III.

-

Perform “PRGRM REINITIALIZE” in WORK SUPPORT mode with CONSULT-III.

-

Cranking engine for at least 15 seconds (starting speed 250 rpm)

-

Perform “WRT DATA AFTR REPLC CPU” in WORK SUPPORT mode with CONSULT-III.

Is the return volume at the fuel injectors more than 20 ml per fuel injector for the starting phase?
NOTE:
•

Do not repeat this procedure more than 3 times and wait 30 seconds between each 15 second cranking
engine.

•

Then wait 30 minutes before cranking the engine for 3 15 second cycles.

•

Follow this instruction so that the starter does not get damaged.

Does the flow measure more than 20ml?

Yes

>> Replace malfunctioning fuel injector.

No

>> GO TO 3.

3.

CHECK FUEL INJECTOR-II

1.

Turn ignition switch OFF.

2.

Reconnect return pipes.

3.

Start Engine.

4.

Select “DATA MONITOR” mode with CONSULT-III.

5.

Check “RAIL PRESSURE” and “RAIL PRES SET” indication.

6.

Does “RAIL PRESSURE” follow “RAIL PRES SET” during the 3 second cranking engine?

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

CHECK GLOW PLUG

1.

Turn ignition switch OFF.

2.

Remove the glow plugs and check for moisture.

3.

If the glow plugs are wet with fuel, it is possible that the fuel injector is leaking.

Are the glow plugs wet with fuel?

Yes

>> Replace malfunction fuel injector.

No

>> Replace high pressure supply pump.

5.

INSPECTION END

Fuel injector system OK.
