To check the injector it is advisable to removethe intake manifold along with throttle body and injector.
The injector should be removed from the manifoldonly if necessary.
For these operations, see the
.
1
- Connect the diagnostic tester dwg.
020460Y. Use the socket in the under-saddle
compartment.
Install the specific tool dwg. 020480Y fuel
pressure check kit.
In this case, the injector can be connected
directly to the tool quick couplings.

-
Prepare a graduated container with
minimum capacity of 100 cm3 and a
resolution of 100 cm3
Connect the injector to the wire supplied with
the injection tester. The wire is provided with
alligator clips for direct connection to the
battery.
Prepare an auxiliary battery.
Set the switch to "ON" with switch to "RUN"
and stand raised.
Select the "active diagnosis" function.
Start the pump diagnosis.
During the first 30 seconds of pump diagnosis,
power the injector by the wire and the auxiliary
battery for 15 seconds.
Collect the fuel delivered by the injector into
the graduated container.
Power supply pressure = 300 KPa (3 BAR)
Quantity delivered = approx. 40 cm3
YES
go to 3
NO
go to 4

-
Perform the injector sealing test.
Dry up the injector outlet by a compressed air
jet. Start the fuel pump. Wait a minute, check
that there are no leaks from the injector outlet.
A light bleeding is normal.
Limit value = 1 drop in 1 minute
YES
go to 5
NO
go to 6
4
-
Higher quantities are not expected.
For lower quantities, replace the injector (THERMAL UNIT AND TIMING SYSTEM).
5
- The injector is conforming.
6
- Repeat the test. If the fault continues, replace the injector (THERMAL UNIT AND TIMING
SYSTEM).
The injector atomisation cannot be checked
by simple methods. The injector is provided
with 5 holes whose angulation forms a jet with
a taper of about 80
degree
The jet thus formed
impinges both intake valves.
NOTE:
- An injector with low flow rate affects the
