Fuel System Purge
If you have run your Td5 dry of fuel and find that you are having difficulty re-starting it, try one of the following purge procedures.
Land Rover official method
If the vehicle runs out of fuel, or the fuel level is
so low that the fuel system draws air into the fuel
rail, the fuel rail will need to be purged before the
engine will start. This can be achieved by
following a set procedure. The process does not
require the use of any specialist equipment and
can be performed by the driver of the vehicle.
The process is as follows:
- Switch off ignition and wait 15 seconds.
- Turn ignition key to position 2 and wait 3
minutes, (this ensures that the fuel system
purges all the air from the fuel rail within the
cylinder head).
- Depress the throttle pedal to more than 90% of
its total travel, (to the throttle stop).
- Crank the engine keeping the throttle pedal
depressed.
NOTE: This operation is controlled by the
ECM and it is important that the purging
operation is not carried out on a vehicle
that has not run out of fuel. If it is carried out
unnecessarily it can lead to the engine flooding
and failing to start.
This operation will be cancelled:
- As soon as engine speed exceeds 600 rev/min.
- The driver allows the throttle pedal to close to a
position less than 90% of its travel.
- The ignition key is released from the start
position.
NOTE: The engine must not be cranked for
more than 30 seconds in any one period.
Repeat the above procedure if the engine fails to
start.
Undocumented & unofficial method
This method is totally unofficial, and I am not to blame for any damage that may occur, not that it should.
- Switch off ignition and wait 15 seconds.
- Turn ignition key to position 2.
- Wait 15 seconds, then repeatedly press and release the throttle pedal until the engine managment warning light starts flashing.
- You will then hear the fuel pump running continuously, this lasts about 3 or 4 minutes.
- After the purge is complete, switch off the ignition for 15 seconds, and then attempt to start the vehicle.
The purge can be cancelled by switching off the ignition.
