B4: CHECK THE POWER SUPPLY CIRCUIT TO THE FUEL PUMP
Reconnect the fuel pump module connector, CA105.
Disconnect the fuel pump connector:
Vehicles with 2.5/3.0 L engine, ROW;
FT02.
Vehicles with 2.5/3.0 L engine, USA;

Turn the ignition switch to the ON position.
Measure the voltage between:
Vehicles with 2.5/3.0 L engine, ROW;
FT02, pin 02 (R) and GROUND.
Vehicles with 2.5/3.0 L engine, USA;
FT06, pin 06 (R) and GROUND.
Is the voltage less than 10 volts?
Yes
INSTALL a new fuel pump module.
REFER to:
Fuel Pump Module - 2.0L NA V6 - AJV6
(310-01 Fuel Tank and Lines, Removal and Installation) /

REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the
system for normal operation.
No
INSTALL a new fuel pump module.
REFER to:
Fuel Pump Module - 2.0L NA V6 - AJV6
(310-01 Fuel Tank and Lines, Removal and Installation) /
Fuel Pump Module - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27
(310-01 Fuel Tank and Lines, Removal and Installation).
CLEAR the DTC, test the system for normal operation.
PINPOINT TEST C : FUEL TRANSFER TEST
WARNING: Use extreme care when carrying out the fuel transfer test not to endanger other road users or infringe any road traffic
regulations. Ideally, this should be carried out away from public roads.
• NOTE: Make sure the fuel tank is between one quarter and half full as indicated by the fuel gauge before beginning this test.
• NOTE: If the 'F2****' value in step 6 of this test is '255', suspect an open or short circuit through the level sensor.
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
C1: CHECK THE 'F2****' VALUES
Turn the ignition switch to the OFF position.
Depress the trip button on the indicator stalk and turn the ignition switch to the ON position.
Continue to hold the trip button in until 'TEST' appears on the instrument cluster display.
Release the trip button.
Press the trip button repeatedly until 'F2****' is displayed (this is the sender value of the transfer fuel pump
module).
Start the engine and drive the vehicle in a tight right-hand circle to transfer fuel from the fuel pump module side of
the fuel tank to the transfer pump module side.
Monitor the 'F2****' value (with assistance, if necessary), and once the value is greater than 60, bring the vehicle
to rest.
Monitor the 'F2****' value over approximately 3 minutes.
Does the 'F2****' value decrease steadily?
Yes
If the 'F2****' value decreases steadily, this indicates that fuel is transferring.
No
If the 'F2****' value does not decrease, or increases, return to the symptom chart and follow the actions listed for
'engine stops with fuel indicated on the gauge'.
PINPOINT TEST D : FUEL PUMP NOISE (VEHICLES WITH 2.5/3.0L ENGINES ONLY)
• NOTE: A certain amount of 'swishing' from the fuel tank is normal as fuel is transferred around the fuel modules.
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
D1: VERIFY THAT THE FUEL PUMP IS THE SOURCE OF THE NOISE

Make sure the gear selector is in the NEUTRAL position for vehicles fitted with manual transmission, PARK position
for vehicles fitted with automatic transmission.
Start the engine and allow to idle.
While the engine is idling, disconnect the main tank harness and monitor the noise (the engine will continue to run
briefly to allow this test to be performed).
Does the noise continue?
Yes
The noise is not caused by the fuel pumps. Clear any DTCs, recheck the system.
No
INSTALL a new fuel pump module,
REFER to:
Fuel Pump Module - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27
(310-01 Fuel Tank and Lines, Removal and
Installation).
CLEAR any DTCs, test the system for normal operation.
PINPOINT TEST E : FUEL STARVATION
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
E1: CHECK FUEL PRESSURE
• NOTE: Petrol vehicles only.
WARNING: This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel
handling precautions. Failure to follow these instructions may result in personal injury.
• NOTE: Vehicles built to Vin: D86654. The fuel pressure can be tested using the Jaguar approved diagnostic system
datalogger facility, or by the use of a suitable gauge from the schraeder connector on the fuel rail.
• NOTE: Vehicles built from Vin: D86655. The fuel pressure can be tested using the Jaguar approved diagnostic system
datalogger facility, or by the use of a suitable gauge from the schraeder connector on the special tool fitted to the fuel
rail.
REFER to:
Fuel System Pressure Check
(310-00 Fuel System - General Information, General Procedures).
• NOTE: The fuel pressure should rise to nominal pressure (320 - 380 Kpa [46 - 55 lb/in²]) within 2 seconds of starting.
Install the fuel pressure gauge to the fuel Schraeder valve.
Apply the parking brake.
Make sure the gear selector is in the NEUTRAL position for vehicles fitted with manual transmission, PARK position
for vehicles fitted with automatic transmission.
Start the engine.
Make sure there are no leaks from the gauge connections
Hold the engine at a steady light throttle and monitor the fuel pressure.
Does the fuel pressure decrease as the throttle is held steady?
Yes
CHECK the following; Visual inspections from this sectionSender function, GO to Pinpoint Test
A.
If this fails to
resolve the issue, install a new fuel pump module,
REFER to:
Fuel Pump Module - 2.0L NA V6 - AJV6
(310-01 Fuel Tank and Lines, Removal and Installation) /
Fuel Pump Module - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27
(310-01 Fuel Tank and Lines, Removal and Installation).
and transfer pump,
REFER to:
Fuel Transfer Pump
(310-01 Fuel Tank and Lines, Removal and Installation).
Clean and flush any heavy contamination from the fuel tank. Clear any DTCs, test the system for normal operation.
No
CHECK the ECM for DTCs indicating another cause for the problem.
PINPOINT TEST F : FUEL CONTAMINATION
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
F1: CHECK FOR THE PRESENCE OF CONTAMINANTS IN THE FUEL
Extract approximately 1 liter of fuel from the rail into a suitable clear container.
Allow to settle for 2 minutes and check for separation of the fuel into layers.
Is there visible separation of the fuel?
Yes
REMOVE the fuel tank. Drain off the fuel. Clean and flush the fuel tank and lines. Refill with fresh fuel. Clear any
DTCs, test the system for normal operation.
No
CHECK the ECM for DTCs indicating another cause for the problem.

• W ARNINGS:
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly
flammable mixtures are always present and can ignite. Failure to follow these instructions may result in personal injury.
This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure
to follow these instructions may result in personal injury.
• CAUTIONS:
Diesel fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute
cleanliness is observed when working with these components. Always fit blanking plugs to any open orifices or lines.
Always carry out the cleaning process before carrying out any repairs to the fuel injection system components. Failure to follow these
instructions may result in foreign matter ingress to the fuel injection system.
