o. Connect SST (wire) to the injector and battery for 15 seconds, and measure the injection volume
with a graduated cylinder. Test each injector 2 or 3 times.
SST 09842-30070
Injection volume:
60 to 73 cm3 (3.7 to 4.5 cu in.) per 15 seconds. Difference between each injector:
13 cm3 (0.6 cu in.) or less
If the injection volume is not as specified, replace the injector.
p. Inspect the fuel leaka
ge.

1. In the condition above, disconnect the tester probes of SST (wire) from the battery and check
the fuel leakage from the injector.
SST 09842-30070
Fuel drop: 1 drop or less per 27 minutes
q. Turn the ignition switch OFF.
r. Disconnect the negative (-) terminal cable from the battery.
s. Remove the SST.

2.INSPECT FUEL PUMP ASSY
a. Inspect the fuel pump resistance.
1. Using an ohmmeter, measure the resistance between terminals 4 and 5.
Standard: 0.2 to 3.0 ohms at 20°C (68°F)
b. Inspect fuel pump operation.
1. Apply battery voltage to both terminals. Check that the pump operates.
