REMOVAL
Remove:
- the air filter,
- the injector gallery (see section 13).
Lift the vehicle.
Remove the strut (1) (to gain access to the bolt
fixing the strut on the right-hand side of the vehi-
cle, remove the mudguard and the right-hand
wheel).

Disconnect the accelerator cable and the electrical
connectors (2) connected to the throttle body.
Remove the bolts and nuts (3) securing the mani-
fold. Lower the vehicle.
Remove the air intake pipe (A) connecting the
throttle body to the air filter.

REMOVAL
Remove the air filter (two mounting bolts at the
top, two mounting nuts at the bottom (1)).
Remove, from above, the two nuts fixing the ex-
haust downpipe to the manifold.
Slacken, without removing it, the nut on the
clamp connecting the downpipe to the exhaust
pipe.
Tilt the exhaust downpipe towards the gearbox.
Remove the nuts securing the manifolds:
- nuts (A) from above,
- nuts (B) from below.

Special note
To remove nut (C) located above the starter mo-
tor, use a small ratchet (6.35 mm square) and a
universal joint.

REFITTING
Replace the manifold gaskets (metal part of the
gasket on the manifold side).
Replace the gaskets between the inlet manifold
and the air filter.
Replace the steel gasket between the exhaust ma-
nifold and the exhaust downpipe.
For the other operations, refitting is the reverse of
removal.

FUEL SUPPLY
Fuel cut off in case of an impact
13
OBJECTIVE
The main function of this feature is to avoid any
fires that may result from the leakage of fuel du-
ring an accident. In order to achieve this, all
components pumping fuel from the fuel tank will
automatically stop functioning during and imme-
diately after the impact. They can then only be
made to operate again by a mechanical action car-
ried out by the driver or the repairer.
DESCRIPTION
The system consists simply of an inertia switch (1),
which:
- detects the impact,
- and thus cuts off the electrical circuit.
13051R
This is fitted:
• in petrol engines, between track 1 of the
pump relay (236) and the + 12 V supply ,
• in diesel engines, between the + supply and
the electrical solenoid (or the coded solenoid
valve if the vehicle is fitted with an engine im-
mobiliser).
OPERATING PRINCIPLE
During the impact, the ball of the inertia switch
moves up and interrupts the electrical connec-
tion.
In petrol engines, the + supply of the pump relay
control circuit (236) is cut. Neither the pump or
the injectors will receive any further supply of
electricity .
The fuel contained in the tank is actually isolated.
In diesel engines, the + supply of the electrical
solenoid or of the coded solenoid is cut off.
The pump can no longer take in fuel, and there is
no longer any high pressure. All risk of fire due to
the outlet of diesel fuel at high pressure onto the
engine is removed.
RESETTING AND OPERATING THE SWITCH
In order to reset the inertia switch, it is sufficient
to press it down in order to replace the ball bea-
ring in its original position .
IMPORTANT: for petrol engines, , having reset
the switch, it is
VITAL to erase the memory of the
computer, using the
XR25. The injection compu-
ter will memorise a pump relay fault once the
system has gone into operation .
