INSPECTION

1.
(a)

FUEL INJECTOR ASSY


Inspect injector resistance.
(1) Using an ohmmeter,measure the resistance between the terminals.
Resistance: 13.4 14.2 at 20C (68F)

(b) Inspect injector inspection


CAUTION:
Keep injector clear of sparks during the test.
(1) Purchase a new fuel tube, and take out the fuel tube
connector from its tube.
HINT:
Part No. 239010D010

Fuel Tube Connector

FUEL SYSTEM

Put the fuel injector into a graduated cylinder.

HINT:
Install a suitable vinyl tube onto the injector to prevent gasoline
from splashing out.
(6) Operate the fuel pump.
(7) Connect SST to the connector of fuel injector.
SST 0984230080
(8) Connect SST to the battery for 15 seconds, and
measure the injection volume with a graduated cylinder. Test the each fuel injector 2 or 3 time.
Injection volume:
60 73 cm3 (3.7 4.5 cu in.) per 15 seconds
Difference between each injector:
13 cm3 (0.8 cu in.) or less
(c)

Inspect leakage
(1) In the condition above, disconnect the test probes
of the from the battery, and check the fuel leakage
from the fuel injector.
Fuel drop: 1 drop or less per 12 minutes

FUEL PUMP
Inspect fuel pump resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
Resistance: 0.2 3.0 at 20C (68F)
(b) Inspect fuel pump operation
(1) Apply battery voltage to both terminals. Check that
the pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent the coil from burning out.

Keep fuel pump as far away from the battery as possible.

Always do the switching at the battery side.
