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 InformationInspection/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 35, 39, 58 and 59.
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.
CAUTION: Affix the fuel injectors firmly to the pipe to prevent any possibility of their movement.
Warning: Be extremely careful when working with fuel. Always work away from sparks and open flames.
3. Ground fuel pump terminal of the DLC by using jumper wire as shown.
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: ONE drop per 2 minutes' pressurization is acceptable.
6. If fuel leaks, replace the fuel injector.
7. Turn the ignition switch to OFF and remove the jumper wire.
Volume Test
1. Remove the fuel injectors together with the distribution pipe.
2. Affix the fuel injectors to the distribution pipe with wire.
Caution: Affix the fuel injectors firmly to the pipe to prevent any possibility of their movement.
Warning: Be extremely cateful when working with fuel. Always work away from sparks and open flames.
3. Connect the SST to the battery and an fuel injector.
4. Check the injection volume with a graduated container.
Injector volumes: 47-68 ml (1.4-2.0 fl oz) /15 sec.
6. If not as specified, replace the fuel injectors.
