INSTALLATION
1. INSTALL FUEL PRESSURE REGULATOR
(a) Apply a light coat of gasoline to a new O-ring, and install
it to the pressure regulator.
(b) Attach the pressure regulator to the delivery pipe.
(c) Check that the pressure regulator rotates smothly.
NOTICE:
If it does not rotate smothly, the O-ring may be pinched, so
remove the pressure regulator and perform again steps (b)
and (c) above.
(d) Install the pressure regulator with the 3 bolts.

ON-VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is a normal operating
noise in proportion to engine speed.
(2) If you have no sound scope, you can check the
injector transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance:
13.4 - 14.2 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
