Component Inspection
INSPECTION1. FUEL INJECTOR ASSY
a. Inspect injector resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 13.4 - 14.2 Ohm at 20 °C (68 °F)
If the resistance is not as specified, replace the injector.
b. Inspect injector.
CAUTION: Keep injector clear of sparks during the test.
1. Purchase the new fuel tube and take out the fuel tube connector from its pipe.
HINT: Part No.23901-28070
2. Connect SST and fuel tube connector to the fuel pipe.
SST 09268-41047 (95336-08070)
CAUTION: Perform connecting operations of the fuel tube connector (quick type) after observing the precautions.
3. Install the O-ring to the injector.
4. Connect SST (union and hose) to the injector, and hold the injector and union with SST (clamp)
SST 09268-41047 (09268-41110, 09268-41300, 95336-08070)
5. Put the injector into a graduated cylinder.
HINT: Install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.
6. Operate the fuel pump.
7. Connect SST to the connector of injector.
8. Connect SST (wire) to the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 time.
SST 09842-30080
NOTE: Always do the switching at the battery side.
If the injection volume is not as specified, replace the injector.
c. Inspect leakage.
1. In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from the injector.
Fuel drop: 1 drop or less per 12 minutes
2. FUEL PUMP ASSY
a. Insect fuel pump resistance.
1. Using an ohmmeter, measure the resistance between terminals.
Resistance: 0.2 - 3.0 Ohm at 20 °C (68 °F)
b. Inspect fuel pump operation
1. Apply battery voltage to both terminals. Check that the pump operates.
NOTE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.
