FUEL INJECTOR INSPECTION

PROCEDURE

1. INSPECT FUEL INJECTOR ASSEMBLY

   1. 

      *a	Component without harness connected (Fuel Injector Assembly)

      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)	12.0 Ω

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

   2. Inspect the fuel injector assembly injection.

      CAUTION:

      Keep the fuel injector assembly away from sparks during the test.

      1. 

         *a	SST (Hose)
         *b	SST (Hose Band)
         *c	SST (Fuel Tube Connector)
         *d	Fuel Pipe (Vehicle Side)

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

      2. Apply a light coat of gasoline to a new O-ring. Then install the O-ring onto the fuel injector assembly.

      3. 

         *1	O-ring
         *a	SST (Hose)
         *b	SST (Hose Band)
         *c	SST (Adapter)
         *d	SST (Clamp)
         *e	Vinyl Tube

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

      4. 

         *a	SST (Tie Band)
         *b	SST (Adapter)
         *c	SST (Clamp)

         Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

      5. Install a vinyl tube onto the fuel injector assembly.

         CAUTION:

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

      6. Set the fuel injector assembly in a graduated cylinder.

      7. Operate the fuel pump.

      8. 

         *a	SST (Wire)
         *b	Connect

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

         Note:

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

         Standard Injection Volume

         Battery Connection	Condition	Specified Condition
         Positive (+) battery terminal - Negative (-) battery terminal	Per 15 seconds	47 to 57 cc (2.9 to 3.5 cu. in.)

         Difference between Each Fuel Injector Assembly

         10 cc (0.6 cu. in.) or less

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

   3. Check for fuel drop.

      1. In the condition above, disconnect SST (wire) from the battery and check for fuel drop from the fuel injector assembly.

         Standard Fuel Drop

         1 drop or less per 51 minutes

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