BASIC INSPECTION : Special Repair Requirement (TEST 2: Internal Fuel Transfer
Pump Check)
INFOID:0000000001162516
NOTE:
CONDITIONS PRIOR TO TEST
- Test 1 Low pressure fuel supply system check has been carried out previously and results are satisfactory.
CAUSE
- Fuel can be seen in the transparent supply pipe leading to the pump.
- However, fuel does not move during starting.
1.CHECK INTERNAL FUEL TRANSFER PUMP
1. Disconnect high pressure supply pump (volumetric control valve) harness connector
2. Remove fuel return pipe from the pump and block it so that it is sealed. Connect a pipe to the pump to
measure the flow of diesel.
3. To authorise a 15 second cranking engine and carry out this test it is essential to carry out the following
procedure: measure the flow of diesel.
- 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)
- Check the flow rate of the fuel being collected in a graduated measuring cylinder (500 ml minimum).The
minimum flow rate must be 25 ml every 15 sec.
- Perform “WRT DATA AFTR REPLC CPU” in WORK SUPPORT mode with CONSULT-III.
Does the flow measure less than 25ml?
Yes >> Replace high pressure supply pump.
No >> GO TO 2.
2.INSPECTION END
