Fuel System Components
INSPECTION1. INSPECT FUEL INJECTOR ASSEMBLY
a. Inspect the resistance of the injector. Using an ohmmeter, measure the resistance between the terminals.
Standard: 13.4 to 14.2 Ohm at 20 °C (68 °F)
If the result is not as specified, replace the injector assembly.
b. Inspect the injector injection.
CAUTION: Keep the injector from sparks during the test.
c. Disconnect the fuel inlet hose (rear fuel pipe) from the fuel main tube.
d. Temporarily install SST (union) to the fuel main tube.
SST 09268-41047 (09268-52011)
e. Tighten the flare nut on the fuel main tube
f. Connect SST (hose) to the SST (union).
SST 09268-41047
g. Install the O-ring to the injector.
h. Connect SST (union and hose) to the injector, and hold the injector and union with SST (clamp).
SST 09268-41047 (09268-41110, 09268-41300)
i. Put the injector into a graduated cylinder.
CAUTION: Install a suitable vinyl hose onto the injector to prevent gasoline from spraying.
j. Connect the hand-held tester to the DLC3.
k. Connect the battery negative (-) cable to the battery.
l. Turn the ignition switch ON, and push the hand-held tester main switch ON.
NOTE: Do not start the engine.
m. Select the ACTIVE TEST mode on the hand-held tester.
HINT: Refer to the hand-held tester operator's manual for further details.
n. If no hand-held tester is available, connect the battery's positive (+) and negative (-) leads to the fuel pump connector
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 cu.cm (3.7 to 4.5 cu in.) per 15 seconds
Difference between each injector: 13 cu.cm (0.8 cu in.) or less
If the injection volume is not as specified, replace the injector.
p. Inspect the fuel leakage.
1. In the condition above, disconnect the SST (wire) tester probes from the battery and check the fuel leakage from the injector.
SST 09842-30070
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.
SST 09268-41047, 09842-30070
5. Disconnect the hand-held tester from the DLC3.
6. Reconnect the fuel inlet hose (rear fuel pipe) to the fuel main tube
