Component Inspection
INSPECTION1. 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.
2. Using a cutter knife, cut the protector of 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 using 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 connect to the fuel pipe (the vehicle side).
SST 09268-41047 95336-08070
CAUTION: Connect the fuel tube connector (quick type) in accordance with to the precautions.
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, 09268-41300,95336-08070)
6. Set the fuel injector in a graduated cylinder.
HINT: Install a suitable vinyl tube onto the injector to prevent gasoline splashes.
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. Inspect 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 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
1. Apply battery voltage to both terminals. Check that the pump operates.
NOTE:
- These tests must be done quickly (for less than 10 seconds) to prevent the coil burnout.
- Keep the fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.
If the motor does not operate, replace the fuel pump.
