Fuel Injector Inspection

Check the resistance.

1. Using an ohmmeter, measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 - 2	20°C (68°F)	11.6 to 12.4 Ω

   If the result is not as specified, replace the injector assembly.
   

Check the operation.

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near a naked flame.

1. Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

2. Install the O-ring onto the fuel injector assembly.
   





3. Connect SST (adapter and hose) to the injector assembly, and hold the injector assembly and union with SST (clamp).

4. Tie the clamp and adapter together with a tie band as shown in the illustration.

5. Set the injector assembly in a graduated cylinder.
   

   CAUTION:

   Install a suitable vinyl tube onto the injector assembly to prevent gasoline from spraying.

6. Operate the fuel pump.
   





7. Connect SST (wire) to the injector assembly and the battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.

   NOTICE:

   Always switch the voltage on and off at the battery side, not the injector side.

   Injection Volume:

   Tester Connection	Condition	Specified Condition
   Positive terminal - Ground terminal	Per 15 seconds	60 to 73 cc (3.7 to 4.5 cu.in.)

   Difference between each injector:

   13 cc (0.8 cu.in.) or less
   

   If the injection volume is not as specified, replace the injector assembly.
   

Check for leaks.

1. Disconnect the test probes of SST (wire) from the battery and check the fuel leaks from the injector.
   

   Fuel drop:

   1 drop or less every 12 minutes
   

   If fuel drop is not as specified, replace the fuel injector assembly.
