Fuel Injector: Testing and Inspection
INSPECTION
1. INSPECT FUEL INJECTOR ASSY
a. Inspect the injector resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 13.4 to 14.2 Ohms at 20°C (68°F)
If the resistance is not as specified, replace the injector.
b. Inspect the injector operation.
CAUTION:
-
This test involves high-pressure fuel and electricity.
-
Take every precaution to ensure safe handling of both the fuel and electricity.
-
Perform this test in a safe area, and avoid any sparks or flame.
-
Do not smoke.
1. Pull out the connector from a new fuel tube.
HINT: Part No. 23901-21060
2. Connect SST and the fuel tube connector to the fuel pipe.
SST 09268-41047 (95336-08070)
CAUTION: After taking the precaution, connect the fuel tube connector (quick type)
3. Install the grommet and O-ring to the injector.
4. Connect SST (union and hose) to the injector, and hold the injector and union with SST (clamp).
