The pressure must be 3 bars ± 0.2.
By applying a pressure of 500 mbars to the
pressure regulator, a fuel pressure of 2.5 bars ±
0.2 should be obtained.

DIESEL EQUIPMENT
General
13
The use of electronic injection in Diesel engines has allowed the operational power of these engines to be
optimised, thus reducing the emission rate of pollutant gases.
The system consists of a computer, which receives information from:
- the coolant temperature sensor,
- the air temperature sensor,
- the engine speed sensor,
- the vehicle speed sensor,
- the load potentiometer,
- the injection start sensor, which forms part of the injector of cylinder n° 3 (injector with sensor).
It controls :
- the injection pump :
• the altimetric corrector (F8Q 630) via a relay
• the advance solenoid valve.
- the cold engine starting system (heater plugs and pre-postheating unit),
- the exhaust gas recycling system (EGR),
- the diesel injection fault warning light,
- the preheating warning light,
- the solenoid valve controlling the fast idle speed LDA,
- the relay controlling the power assisted steering electric pump assembly (for vehicles with air conditio-
ning), the pump assembly is supplied once the engine speed exceeds 650 rpm.
It carries out a self diagnosis procedure which may be visualised through the
XR25.
SPECIAL FEATURES
On the injection pump it is possible to replace:
- the load potentiometer,
- the advance solenoid valve,
- the altimetric corrector,
- the electrical solenoid.

To remove the terminals from the pump
connector :
1) Pull the yellow guide to release the terminal
connectors, then press on the two tabs on
each side of the connector.
2) Extract the yellow guide.
3) Pull the wire to be removed.
4) The terminal connector is secured by two
tabs, one on each side ; using a screwdriver,
move one of these to one side (the action of
pulling on the wire prevents the tab from
going back into place).
5) Using a screwdriver, move the other tab to
one side.
The terminal connector can now be removed from
the connector.Remove the protective sheath grouping the pump
actuators.
Remove the protective cover from the solenoid
valve.
Remove the solenoid valve using tool Mot. 997-
