Fuel Injector: Testing and Inspection
INSPECT FUEL INJECTOR ASSEMBLY
a. Inspect injector resistance
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 11.6 - 12.4 Ohm at 20°C (68°F)
If the resistance is not as specified, replace the injector.
b. Inspect injector
CAUTION: Keep injector clear of sparks during the test.
1. Obtain the new No.1 fuel pipe (part No. 23801-31070) and take out the fuel tube connector from the pipe.
2. Install the fuel tube connector to a SST (hose), then connect the tube connect and fuel pipe.
SST 09268-41047 (95336-08070)
