Inspection
Operation check
1. Warm up the engine and run it at idle.
2. Listen for operational sound of each injector with a screw-
driver or a sound scope.
3. If no sound is heard, measure injector resistance.
4. If the injector resistance is OK, check wiring to the injector
and the voltages of the ECU terminals MTX (2A, 2U and
2V) ATX (3A, 3U and 3V).
(Refer to page F-152.)
Injector resistance
1. Disconnect the injector harness.
2. Measure resistance of the injector with an ohmmeter.
Resistance: 12-l 6Q
3. If not as specified, replace the injector.

Removal
Warning
l Before performing the following operation, release
the fuel pressure from the fuel system to reduce the
possibility of injury or fire. (Refer to page F-121 .)
l When removing the fuel system components, keep
sparks, cigarettes, and open flames away from the
fuel.
1. Disconnect the connectors from the injectors.
2. Remove the injector harness from the delivery pipe.
3. Remove the bolts from the intake manifold.
4. Remove the delivery pipe with the injectors and the pres-
sure regulator.
5. Remove the injectors, grommets, and insulators.
F-131

l Be extremely careful when working with fuel. I
23UOFX.121 Always work away from sparks or open flames.
3. Connect the diagnosis connector terminals F/P and GND
with a jumper wire.
FUEL SYSTEM
Fuel leakage test
1. Remove the injectors with the delivery pipe.
(Refer to page F-l 31.)
2. Affix the injectors to the delivery pipe with wire.
Caution
l Affix the injectors firmly to the delivery pipe so that
no movement of the injectors is possible.

Warning
4. Turn the ignition switch ON.
03UOFX-16’
23UOFX-12 9 5. Tilt the injectors approx. 60 degrees and verify that no fuel
leaks from the injector nozzles.
6. If fuel leaks from an injector, replace it.
Note
l After 1 minute a small amount of fuel leakage from
the injector Is acceptable.
7. Turn the ignition switch OFF and remove the jumper wire.

3. Warm-up the engine to normal operating temperature and
run it at idle.
Warning
l Confirm that transmission is in Neutral (MTX) or P
range (ATX).
