FUEL INJECTOR(for Port Injection) INSPECTION

PROCEDURE

INSPECT FUEL INJECTOR ASSEMBLY

Check the resistance.

*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)	11.6 to 12.4 Ω

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

Check the operation.

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

Remove the EFI fuel pipe clamp from the fuel tube connector.
Disconnect the No. 2 fuel tube sub-assembly from the fuel pipe.

*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).

SST: 09268-31014 ( 09268-41500, 09268-41700, 95336-08070 )

Note

Ensure that the SST (fuel tube connector) O-rings are not damaged and are free of foreign matter as they are used to seal the connections between the fuel tube connector and fuel pipe.

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

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

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

SST: 09268-31014 ( 09268-41600, 09268-41300, 09268-41700, 95336-08070 )

*a Lock

*b SST (Tie Band)

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

SST

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 wear, damage or cracks. If there are any abnormalities, replace SST.
Tech Tips

When removing SST (tie band), disengage the lock.
Check that SST (clamp) and SST (adapter) cannot be easily separated.
Install a vinyl tube to the fuel injector assembly.

CAUTION:

Install a suitable vinyl tube to the fuel injector assembly to prevent fuel from spraying.
Set the fuel injector assembly into a graduated cylinder.
Operate the fuel pump with filter assembly.

*a	SST (EFI Inspection Wire I)

Connect SST (EFI inspection wire I) 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.

SST: 09842-30090

Standard Injection Volume

Tester Connection	Condition	Specified Condition
Positive (+) terminal - Ground terminal	Per 15 seconds	84 to 101 cc (5.1 to 6.2 cu. in.)

Difference between Each Fuel Injector Assembly
17 cc (1.0 cu. in.) or less

Note

Make sure that SST (EFI inspection wire I) is securely connected.
Always switch the voltage on and off at the battery side, not the fuel injector assembly side.

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

Check for leaks.
1. Disconnect SST (EFI inspection wire I) from the battery and check for fuel leaks from the fuel injector assembly.
  
  Standard Fuel Drop
  
  1 drop or less per 25 minutes
  
  If the result is not as specified, replace the fuel injector assembly.
2. Connect the No. 2 fuel tube sub-assembly.
