Cold Start Injector: Testing and Inspection

ON-VEHICLE INSPECTION





INSPECT RESISTANCE OF COLD START INJECTOR
(a) Remove the throttle body.
(b) Disconnect the cold start injector connector.
(c) Using an ohmmeter, measure the resistance between the terminals.

Resistance: 2 - 4 ohms

If the resistance is not as specified, replace the injector.
(d) Reconnect the cold start injector connector.
(e) Reinstall the throttle body.

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 (G) cable.





(f) Using a service wire, short terminals +B and FP of the check connector.
(g) Turn the ignition switch ON.

NOTE: Do not start the engine.





(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 minute

(b) Disconnect the battery negative (-) cable.
(c) Remove SST and the service wire.
