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 injector connector power
terminal and body .
4. CHECK OUTPUT SIGNAL FROM ECU .
1) Connect fuel injector connector of all .
2) Measure voltage between ECU connector terminals
and body.
