PROCEDURE
INSPECT PORT FUEL INJECTOR ASSEMBLY
Check the resistance.
| *a | Component without harness connected (Port Fuel Injector Assembly) |
Measure the resistance according to the value(s) in the table below.
| Standard Resistance | ||||||
|---|---|---|---|---|---|---|
|
If the result is not as specified, replace the port fuel injector assembly.
Check the operation.
CAUTION:
Work procedures must be performed in an area with good ventilation (airflow), and flames or other things that could act as ignition sources must not be present.
Vaporized fuel could ignite, resulting in a serious accident.
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).
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 port 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 port fuel injector assembly, and hold the port fuel injector assembly and union with SST (clamp).
| *a | Lock |
| *b | SST (Tie Band) |
Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.
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 port fuel injector assembly.
Note
Install a suitable vinyl tube to the fuel injector assembly to prevent fuel from spraying.
Set the port 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 port fuel injector assembly and battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each port fuel injector assembly 2 or 3 times.
| Standard Injection Volume | ||||||
|---|---|---|---|---|---|---|
|
| Difference between Each Port 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 port fuel injector assembly side.
If the injection volume is not as specified, replace the port fuel injector assembly.
Check for leaks.
Disconnect SST (EFI inspection wire I) from the battery and check for fuel leaks from the port fuel injector assembly.
| Standard Fuel Drop |
|---|
| 1 drop or less per 25 minutes |
If the result is not as specified, replace the port fuel injector assembly.
Connect the No. 2 fuel tube sub-assembly.
Install the EFI fuel pipe clamp to the fuel tube connector.
Check for fuel leaks.
