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 .

SPECIAL TOOLING REQUIRED

unions
EQUIPMENT REQUIRED
2 000 ml measuring cylinder
It is advised to check the pump supply flow
through the fuel return pipe connected to the
pump-fuel sender unit assembly.
IMPORTANT
During this operation, it is essential :
• to refrain from smoking and handling incan-
descent objects close to the working area,
• to take precautions against possible fuel
projections which may occur due to the resi-
dual pressure in the supply pipes when they
are removed.

CHECKING THE PUMP FLOW
Disconnect the fuel return pipe (1) (Mot. 1265).
Connect a piece of pipe to the hose and place this
into a 0-2 000 ml graduated measuring cylinder.
Shunt terminals (3) and (5) of relay (K) on the DF7
engine, or for the
E7J engine shunt at (L) on the
fuel pump relay (which is located in the engine
fuse box ). In one minute, the pump flow must be
a minimum of 1.3 litres with a voltage of 12
volts.
If the fuel flow is low, check the pump feed vol-
tage (approximately 10 % reduction in flow for a
voltage drop of 1 Volt)
