Inspection

INSPECTION




1. INSPECT FUEL INJECTOR ASSEMBLY
a. Check the resistance.




1. Using an ohmmeter, measure the resistance between the terminals.
If the result is not as specified, replace the fuel injector.




b. Check the injection volume.

NOTE:
- Perform the test in a well-ventilated area and watch out for flames.
- Handle the fuel tube connector carefully.

1. Prepare a new fuel tube.

HINT: Part No. 23901-28290

2. Using a cutter knife, cut the fuel tube protector as illustrated. Tear the protector by hand, then remove the fuel tube connector.

NOTE: If the protector is cut too deeply with the cutter, the O-ring of the fuel tube connector will be damaged.




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

SST 09268-41047 (95336-08070)




4. Install a new O-ring onto the fuel injector.
5. Install SST and the vinyl tube onto the fuel injector.

SST 09268-41047 (09268-41110, 09268-41300)




6. Set the fuel injector in a graduated cylinder.
7. Actuate the fuel pump
8. Install SST onto the fuel injector.

SST 09842-30080

9. Connect SST to the battery, then measure the injection volume for 15 seconds. Perform the inspection 2 or 3 times, then calculate the average.






NOTE: Always do the switching at the battery side. If the result is not as specified, replace the fuel injector.




c. Check the leakage.
1. When inspecting the injection volume, remove SST from the battery. Inspect the fuel leakage from the fuel injector.

Standard: 1 drop or less every 12 minutes

If the result is not as specified, replace the fuel injector.




2. INSPECT FUEL PUMP
a. Check the resistance.




1. Using an ohmmeter, measure the resistance between the terminals.
If the result is not as specified, replace the fuel pump.




b. Check the operation.
c. Check that the motor operates when battery voltage is applied across the terminals.

NOTE:
- Perform the check quickly (for less than 10 seconds).
- Keep the battery as far away from the fuel pump as possible.
- Always do the switching at the battery side.
If the motor does not operate, replace the fuel pump.
