Check Operation Of Each Fuel Injector; Check Voltage Of Power Supply For Fuel Injector; Check Fuel Injector; Check Signal On Ecu - Subaru SVX 1992 Manual

FUEL INJECTION SYSTEM
[T8E5] 2-7
1 . CHECK OPERATION OF EACH FUEL INJEC-
TOR.
While cranking the engine, check that each fuel injector
emits 'operating' sound .
Use a sound scope or attach a screwdriver to injector
for this check.
2. CHECK VOLTAGE OF POWER SUPPLY FOR
FUEL INJECTOR.
1) Turn ignition switch to "OFF".
2) Disconnect connector from each fuel injector .
3) Measure voltage between each injector connector
terminal and body .
Connector & Terminal/Specified voltage
#1 : (E5) No. 2 - Body/10 V, min .
#2 : (E8) No. 2 - Body/10 V, min.
#3: (E6) No. 2 - Body/10 V, min .
#4: (E9) No. 2 - Body/10 V, min .
#5 : (E7) No. 2 - Body/10 V, min .
#6 : (E10) No. 2 - Body/10 V, min.

4. CHECK SIGNAL ON ECU.
1) Connect connectors onto each fuel injector .
2) Turn ignition switch to "ON" .
3) Measure voltage between ECU connector terminals
and body .
