   Standard injection volume: 76 to 92cm ³  (4.6 to 5.6 cu in.) per 15 seconds 

   Standard difference between each injector: 16 cm ³  (1.0 cu in.) or less

1. Disconnect the SST (wire) tester probes from the battery and check the fuel leakage from the injector.

   Standard fuel drop: 1 drop or less per 12 minutes 

2. Turn the ignition switch OFF.
3. Disconnect the cable from the negative (-) battery terminal.
4. Remove SST.
