3 - Perform the injector sealing test.
Dry the injector outlet with a blast of compressed
air. Activate the fuel pump. Wait for one minute,
making sure there are no leaks coming from the
injector. Slight oozing is normal.
Value limit = 1 drop per minute
YES go to 5 NO go to 6
4 - Higher quantities are not expected.
For lower quantities, replace the injector (THER-
MAL GROUP AND TIMING SYSTEM).
5 - The injector is conforming.
6 - Repeat the test. If the fault continues, replace
the injector (THERMAL GROUP 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°. The jet thus formed impinges both in-
take valves.
N.B.
- AN INJECTOR WITH LOW FLOW RATE AFFECTS THE
MAXIMUM PERFORMANCE.
- AN INJECTOR WITH POOR SEAL AFFECTS IDLING AND
THE START-UP FEATURES AFTER A SHORT STOP WITH
HOT ENGINE.
- IN CASE OF CLOGGING OF THE INJECTOR, IT IS NEC-
ESSARY TO REPLACE IT, ALONG WITH THE FUEL FILTER
CONTAINED IN THE TANK. CAREFULLY CLEAN THE SYS-
TEM AND THE TANK.
Troubleshooting
1 - A failure of the EMS system is more likely to be due to the connections than to the components.
Before searching the EMS system for failures, perform the following checks:
SUGGESTION FOR TROUBLESHOOTING
Specification

1 1. Power supply - Battery voltage
- Burnt fuse
- Remote control switches
- Connectors
2 2. Chassis earth
