Fuel Injector: Testing and Inspection
INSPECTION
1. INSPECT FUEL INJECTOR ASSEMBLY
a. Inspect injector resistance
1. Using an ohmmeter, measure the resistance between the terminals.
Standard Resistance: 13.4 to 14.2 Ohms at 20 degree C (68 degree F)
If the resistance is not as specified, replace the injector.
b. Inspect injector operation.
CAUTION: This test involves high-pressure fuel and electricity. Take every precaution regarding safe handling of both the fuel and the
electricity. Preform this test in a safe area, and avoid any sparks or flame. Do not smoke.
1. Obtain new No. 1 fuel pipe (part No. 23801-20171) and remove the fuel tube connector from the pipe.
2. Install the fuel tube connector to SST (hose), then connect the tube connector and the fuel pipe.
