Component Inspection
INSPECTION1. INSPECT FUEL INJECTOR ASSEMBLY
a. Check the injector resistance.
1. Measure the resistance between the terminals.
Standard: 13.4 to 14.2 Ohms at 20°C (68°F)
If the result is not as specified, replace the injector.
b. Check the injector injection.
CAUTION:
- This test involves high pressure fuel and electricity.
- Take every precaution regarding safe handling of both the fuel and the electricity.
- Perform this test in a safe area, and avoid any sparks or flame.
- Do not smoke.
1. Purchase the new fuel tube and take out the fuel tube connector from its pipe.
Fuel tube: Parts No. 23801-20190
2. Connect SST and the fuel tube connector to the fuel pipe.
CAUTION: Always read the precautions before connecting the fuel tube connector (quick type).
3. Install the O-ring to the injector.
4. Connect SST (union and hose) to the injector, and hold the injector and the union with SST (clamp)
5. Put the injector into a graduated cylinder.
HINT: Install a suitable vinyl tube onto the injector to contain the gasoline spray.
6. Operate the fuel pump.
Standard:
7. Connect SST (wire) to the injector and the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times.
SST 09842-30070 Standard:
NOTE: Always turn on and off the voltage on the battery side, not the fuel pump side.
If the injection volume is not as specified, replace the injector.
c. Check fuel 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. INSPECT FUEL PUMP
a. Check the fuel pump resistance.
1. Measure the resistance between the terminals.
Standard: 0.2 to 3.0 Ohms at 20°C (68°F)
b. Check fuel pump operation.
1. Apply battery voltage to both the terminals. Check that the pump operates.
NOTE:
- These tests must be done within 10 seconds to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.
- Always turn on and off the voltage on the battery side, not the fuel pump side.
