NOTICE:
·

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.



HINT:

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



v.

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


vi.

Install a vinyl tube to the injector.

NOTICE:

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



vii.

Put the injector into a graduated cylinder.


viii.

Operate the fuel pump.

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.

SST
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


NOTICE:
·

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.



c.

Check for fuel drop.

i.
A196009

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.
