FUEL INJECTOR INSPECTION
PROCEDURE
INSPECT FUEL INJECTOR ASSEMBLY
Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection
Condition
Specified Condition
1 - 2
20°C (68°F)
11.6 to 12.4 Ω
If the result is not as specified, replace the fuel injector assembly.
Inspect the fuel injector injection.
CAUTION:Keep the fuel injector assembly away from sparks during the test.

Install a vinyl tube onto the fuel injector assembly.
CAUTION:Install a suitable vinyl tube onto the fuel injector assembly to prevent fuel from spraying.
Put the fuel injector assembly into a graduated cylinder.
Operate the fuel pump.
-
*a
SST (Wire)
*b
Connect
Connect SST (wire) to the fuel injector assembly and the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each fuel injector assembly 2 or 3 times.

Note:Always switch the voltage on and off at the battery side, not the fuel injector assembly side.
Standard Injection Volume
Tester Connection
Condition
Specified Condition
Positive terminal - Ground terminal
Per 15 seconds
60 to 73 cc (3.7 to 4.5 cu. in.)
Difference between each fuel injector assembly
13 cc (0.8 cu.in.) or less
If the result is not as specified, replace the fuel injector assembly.
-
Check for fuel drop.
In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel drop from the fuel injector assembly.
Standard fuel drop
1 drop or less per 12 minutes
If the result is not as specified, replace the fuel injector assembly.
