FUEL INJECTOR INSPECTION

PROCEDURE

1. INSPECT FUEL INJECTOR ASSEMBLY

   1. 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 fuel injector assembly.

   2. Inspect the injector injection.

      CAUTION:

      Keep the injector away from sparks during the test.

      1. 

         *1	SST (Hose)
         *2	SST (Hose Band)
         *3	SST (Fuel Tube Connector)
         *4	Fuel Pipe

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

         09268-41500

         09268-41700

         95336-08070

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

      3. 

         *1	SST (Hose)
         *2	SST (Hose Band)
         *3	SST (Adapter)
         *4	O-Ring
         *5	SST (Clamp)
         *6	Vinyl Tube

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

         09268-41110

         09268-41300

         09268-41700

         95336-08070

      4. 

         *1	SST (Tie Band)
         *2	Lock

         Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).

         09268-31014

         09268-41800

         Note:

         • As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

         • Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.

         Tip:

         When removing SST (tie band), disengage the lock.

      5. Check that SST (clamp) and SST (adapter) cannot be easily separated.

      6. Install a vinyl tube to the injector.

         Note:

         Install a suitable vinyl tube to the fuel injector assembly to contain any gasoline spray.

      7. Put the injector into a graduated cylinder.

      8. Operate the fuel pump.

      9. 

         *1	SST (EFI Inspection Wire H)
         	Connect

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

         09842-30080

         Standard injection volume

         88 to 106 cc (5.4 to 6.5 cu. in.) every 15 seconds

         Standard difference between each injector

         16 cc (1.0 cu. in.) or less

         Note:

         • Make sure that SST (EFI inspection wire H) is securely connected.

         • Always do the switching at the battery side.

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

   3. Check for fuel drop.

      1. 

         In the condition above, disconnect the tester probes of SST (EFI inspection wire H) from the battery and check for fuel drop from the fuel injector assembly.

         Standard fuel drop

         1 drop or less every 20 minutes

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