Fuel Tank and Lines

Inspection And Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

Mechanical Electrical
Damaged fuel lines Fuses (see table)
Damaged push connect fittings Loose or corroded electrical connectors
Fuel leaks Fuel pump module
Damaged fuel tank filler pipe cap Rear electronic module
Damaged fuel tank filler pipe Fuel pump relay

3. Verify the following systems are working correctly:
- Air intake system
- Cooling system
- Charging system
- Ignition system

4. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
5. If the cause is not visually evident and the Jaguar approved diagnostic system is not available, use a fault code reader to retrieve the fault codes before proceeding to the diagnostic trouble code (DTC) index.
6. Where the Jaguar approved diagnostic system is available, complete the S93 report before clearing any or all fault codes from the vehicle.

NOTE: If a DTC cannot be cleared, then there is a permanent fault present that flags again as soon as it is cleared (the exception to this is P1260, which will only clear following an ignition OFF/ON cycle after rectification).

7. Using the Jaguar approved diagnostic system where available, and a scan tool where not, check the freeze frame data for information on the conditions applicable when the fault was flagged. The format of this will vary, depending on the tool used, but can provide information useful to the technician in diagnosing the fault.

Control module Power and Ground supplies
DTCs can be set if a module's power or ground supply is interrupted.
Check the fuses listed in the table below, and check the power and ground circuit pinpoint tests before condemning components.
