Injector Volume Test

WARNING: Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Always carry out the following procedure with the engine stopped.

NOTE:
- Perform the following inspection only when directed.
- If there is an after market fuel injector tester or the SST (49 L018 901), perform this inspection.
- If there is no after market fuel injector tester or the SST, perform "Simulation Test", "Resistance Inspection" and "Fuel Leakage Inspection" to verify whether the fuel injector is okay or not.

1. Complete the "BEFORE REPAIR PROCEDURE".
2. Disconnect the negative battery cable.

Using the SST
1. Remove the fuel injector together with the fuel distributor.
2. Fasten the fuel injectors firmly to the fuel distributor with wire.




3. Connect the SST as shown in the figure.




4. Remove the fuel pump relay.

CAUTION: Connecting the wrong fuel pump relay socket terminals may possibly cause a malfunction. Carefully connect the specified terminal only.




5. Short the pump relay socket terminal 30 to the body GND using a jumper wire.

CAUTION: Before connecting the negative battery cable be sure all fuel connections, clamps and fittings are secure. Fuel pump will operate at full pressure anytime the cable is connected to the battery. When the cable makes contact, It is sure to arc and create a danger of Ignition or explosion.

6. Connect the negative battery cable to operate the fuel pump.
7. Measure the injection volume of each fuel injector by using a graduated container.

Injection volume: 47 - 68 ml {47 - 68 cc, 1.4 - 2.0 fl oz}/15 sec.

8. Disconnect the negative battery cable and remove the jumper wire.
- If not as specified, replace the fuel injector.

9. Complete the "AFTER REPAIR PROCEDURE".

Using a Fuel injector Tester
1. Remove the fuel injectors.
2. Connect the fuel injector to a fuel injector tester.

3. Measure the injection volume of each fuel injector.
- If not as specified, replace the fuel injector.

Injection volume: 47 - 68 ml {47 - 68 cc, 1.4 - 2.0 fl oz}/15 sec.

4. Complete the "AFTER REPAIR PROCEDURE".
