Warning: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedures". Technician Safety Information




Inspection/Operation check
1. Warm up the engine and let it idle.
2. Listen for the operational sound of each fuel injector with a screwdriver or a sound scope.
3. If no sound is heard, measure fuel injector resistance.
4. If the fuel injector resistance is OK, check wiring to the fuel injector and the voltages of the ECM terminals 2U, 2V, 2Y and 2Z.




Inspection/Fuel injector resistance
1. Disconnect the fuel injector harness.
2. Measure resistance of the fuel injector.

Resistance: 12-16 Ohms (at 20°C {68°F})

3. If not as specified, replace the fuel injector.




Fuel Leakage Test
1. Remove the fuel injectors together with the fuel distributor.
2. Fasten the fuel injectors firmly to the pipe.

Warning: Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.




3. Connect the data link connector terminals F/P and GND with a jumper wire.
4. Turn the ignition switch ON.




5. Tilt the fuel injectors approximately 60 degrees and verify that no fuel leaks from the fuel injector nozzles.

Leakage Specification: If there is more than one drop per 2 minutes, replace the fuel injector.

6. Turn the ignition switch to OFF and remove the jumper wire.




Volume Test
1. Remove the fuel injectors together with the fuel distributor.
2. Affix the fuel injectors to the distribution pipe with wire.
3. Fasten the fuel injectors firmly to the pipe.




4. Connect the SST to the battery and an fuel injector.
5. Check the injection volume with a graduated container.

Injector volumes: 47-68 ml (47-68 cc, 1.4-2.0 fl oz) /15 sec.

6. If not as specified, replace the fuel injectors.
