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 ±

CHECKING THE FUEL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with a pressure
gauge 0; + 10 bar tool kit)
Mot. 1311-05 Junction tool (for union J)
IMPORTANT : during the opening of the fuel cir-
cuit , be sure to use a cloth to avoid possible pro-
jections of fuel due to the residual pressure.
Disconnect the fuel supply pipe.
Fit tool Mot. 1311-04 on the injector gallery, then
reconnect the fuel supply pipe to the tool itself.

Monitoring mode
Water temperature≥ 101°C

Exit from monitoring mode
The monitoring mode is left 2 minutes after switching off the ignition in cases where the coolant
temperature is not greater than or equal to 101°C or once the coolant temperature falls below 92°C.

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.
