aCheck the high pressure circuit (see 13B, Diesel in-
jection, High pressure pipe: Check, page 13B-34)
.
aUse the Diagnostic tool to check for an absence of
stored faults; deal with these and clear them as nec-
essary.
aRefit the engine cover.
REPLACING THE HIGH PRESSURE PUMP
aIf replacing the high pressure pump, reprime the die-
sel circuit using the Diagnostic tool.
aConnect the Diagnostic tool to the vehicle.
aConnect to the diesel injection computer.
aRun command AC212 « NEW PUMP CHAMBER
FILLING » (see Fault finding - Replacement of
components) (13B, Diesel injection).
aFollow the instructions on the Diagnostic tool until
the command is completed.
aStart the engine.
aIf the engine does not start or if the startup sequence
is interrupted:
-switch off the ignition,
-wait 30 seconds,
-restart the engine.
aUsing the Diagnostic tool, clear any faults stored in
the diesel injection computer.Note:
Never start the engine until the pump has been
reprimed.
Also comply with the operation instructions pro-
vided to prevent the high pressure pump from
being damaged internally, due to running with no
load and no diesel lubrication.
Note:
The starting phase may last up to 20 seconds.

I - CHECKING THE FUEL VAPOUR ABSORBER
aOn the fuel vapour absorber, plug the circuit coming
from the fuel tank.
aConnect the pressure gauge of the (Mot. 1311-01)
to the fuel vapour absorber breather outlet.
aWith the engine at idle speed, check that no vacuum
is present at the fuel vapour absorber breather out-
let. In the same way, the control value read by the
Diagnostic tool in parameter « fuel vapour absorb-
er bleed solenoid valve OCR » remains minimal X
less than or equal to 1.5%.
Is there a vacuum?
-Yes: With the ignition off, use a manual vacuum
and pressure pump to apply a vacuum of 500
mbar to the solenoid valve outlet. The vacuum
pressure should not vary by more than 10 mbar
over 30 seconds.
•Does the pressure vary?
-Yes: the solenoid valve is faulty, replace it (see
17B, Petrol injection, Petrol injection: List
and location of components, page 17B-1) .
-No: if it is an electrical problem, check the circuit
(see MR 413 Fault finding, 17B, Petrol injec-
tion, Fault finding - Interpretation of faults,
Canister bleed solenoid valve circuit).
-No: In bleeding condition (see « bleeding
condition » ), the vacuum should increase. In the
same time, the value of the parameter on the Diag-
nostic tool increases.
II - CHECKING THE FUEL VAPOUR ABSORBER-
TANK CONNECTION
aCheck this connection by connecting a manual vac-
uum and pressure pump to the pipe leading to the
fuel vapour absorber.Special tooling required
