Cold Start Injector: Testing and Inspection
ON-VEHICLE INSPECTIONINSPECT RESISTANCE OF COLD START INJECTOR.
a. Disconnect the cold start injector connector.
b. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 2 - 4 ohms.
If the resistance is not as specified, replace the injector.
c. Reconnect the cold start injector connector.
OFF-VEHICLE INSPECTION
1. INSPECT INJECTION OF COLD START INJECTOR.
WARNING: Keep clear of sparks during the test.
a. Install SST (union) to the injector and delivery pipe with new gaskets and the union bolts.
*SST 09268-41045
b. Connect the unions with SST (hose).
*SST 09268-41045
c. Connect SST (wire) to the injector.
*SST 09842-30050
d. Put a container under the injector.
e. Reconnect the battery negative (-) cable.
f. Turn the ignition switch "ON".
NOTE: Do not start the engine.
g. Using a service wire, short terminals +B and FP of the check connector.
h. Connect the test probes of the SST (wire) to the battery, and check that the fuel spray is as shown.
*SST 09842-30050
CAUTION: Perform this within the shortest possible time.
2. INSPECT LEAKAGE.
a. In the condition above, disconnect the test probes of SST (wire) from the battery and check fuel leakage from the injector.
*SST 09842-30050
Fuel drop: One drop or less per minutes
b. Disconnect the battery negative (-) cable.
c. Remove SST and the service wire.
