Component Inspection

INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY
a. Inspect injector resistance.
Using an ohmmeter, measure the resistance between the terminals.

Resistance: 11.6 to 12.4 Ohms at 20°C (68°F)

If the resistance is not as specified, replace the injector.

b. Inspect the injection volume.

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 flames. Do not smoke.




1. Install the fuel tube connector to SST (hose), then connect the tube connector to the fuel pipe (vehicle side).

SST 09268-41048 (95336-08070, 09268-41500)




2. Install the O-ring to the fuel injector.
3. Connect SST (adaptor and hose) to the injector, and hold the injector and union with SST (clamp).

SST 09268- 41048 (09268- 41130, 90467- 13001), 09268-41400

4. Put the injector into the graduated cylinder.

CAUTION: Install a suitable vinyl tube onto the injector to contain gasoline spray.

5. Operate the fuel pump.




6. Connect SST (wire) to the injector and the battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.

SST 09842-30080
Volume: 84 to 100 cu.cm (5.1 to 6.0 cu in.) in 15 seconds
Difference between each injector:
16 cu.cm (0.96 cu in.) or less

If the injection volume is not as specified, replace the injector.

c. Check for leakage.




In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel leakage from the injector.

Fuel drop: 1 drop or less in 16 minutes

2. INSPECT FUEL PUMP




a. Inspect fuel pump resistance.
Using an ohmmeter, measure the resistance between the terminals.
Resistance: 0.2 to 3.0 Ohms at 20°C (68°F)

If the result is not as specified, replace the fuel pump assembly.

b. Inspect fuel pump operation.
Apply battery voltage to both the terminals. Check that the pump operates.

NOTE:
- These tests must be done quickly (within 10 seconds) to prevent damage to the pump.
- Keep fuel pump as far away from the battery as possible.
- Always switch at the battery side.

If the pump does not operate, replace the fuel pump assembly.
