Cold Start Injector Testing

COLD START INJECTOR




MEASURE RESISTANCE OF COLD START INJECTOR
1. Disconnect the cold start injector connector.
2. Using an ohmmeter, check the resistance between the terminal.

Resistance: 2-4 kohms

If the resistance is not as specified, replace the cold start injector.
3. Reconnect the cold start injector connector.

CHECK COLD START INJECTION
1. Disconnect cable from negative (-) terminal of battery.




2. Disconnect cold start injector connector.

CAUTION: Keep clear of sparks during the test.




(a) Install a gasket, fuel pipe, another gasket and union bolt to the injector.
(b) Connect SST (09842-30055), (wire) to injector.
(c) Put a container under the injector.
(d) Turn the ignition switch to ON.

NOTE: Do not start the engine.




(e) Using SST (09843-18020), connect terminals FP and +B of the check connector.




(f) Connect the test probes of the SST (09842-30055), to the battery and check that the fuel spray is as shown.

NOTE: Perform this check within the shortest possible time.

3. Check cold start injector for leakage:
(a) Put a suitable container or shop towel under the fuel pipe.
(b) Remove the union bolt and two gaskets, and disconnect the fuel pipe.

NOTE: Slowly loosen the union bolt.

(c) Remove the two bolts and cold start injector and the gasket.




(g) Disconnect the test probes from the battery and check that there is less than one drop of fuel per minute from the injector.
(h) After checking, remove SST and restore the following parts to their original condition.
- Check connector
- Ignition switch OFF
- Cold start injector
- Injector connector




INSTALLATION OF COLD START INJECTOR
1. Place on a new gasket and install the cold start injector with the two bolts.

Torque: 55 kg/cm (48 in.lbs., 5.4 Nm)

2. Using new gaskets, connect the fuel tube with the union bolts.

Torque: 200 kg/cm (14 ft.lbs., 20 Nm)

3. Connect cold start injector connector.
4. Connect cable to negative (-) terminal of battery.
5. Check for fuel leakage.
