Removal and Installation
CAUTION:
The accelerator wire should be adjusted when removing and replacing any parts of the accelerator
control system, shown in the illustration.
a. Warm up engine to normal operating temperature. Then stop it.
b. Check to see if throttle valve fully opens when accelerator pedal is fully depressed and if it returnsto idle position when released.
c. Adjust accelerator pedal free play by turning adjusting nut.
d. Check accelerator control parts for improper contact with any adjacent parts.
e. When connecting accelerator wire, be careful not to twist or scratch its inner wire.
f. Apply a light coat of recommended multi-purpose grease to all sliding or friction surfaces. Do not apply grease to wire.
g. For ASCD wire adjustment, refer to ªASCD Wire Adjustmentº in EL section.
INSPECTION AFTER INSTALLATION
I Check if accelerator pedal moves smoothly within its range.
I Check if accelerator pedal returns securely to its original position.
I Perform ªAccelerator Pedal Released Position Learningº when removing the accelerator pedal position
sensor harness connector. Refer to ªBASIC SERVICE PROCEDUREº in EC section for instructions.

WARNING:
When replacing fuel line parts, be sure to observe the following:
IDisplay a ªCAUTION: INFLAMMABLEº sign in workshop.
I Be sure to furnish workshop with a CO
2fire extinguisher service.
I Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
I Be sure to disconnect battery ground cable before conducting operations.
I Pour drained fuel into an explosion-proof container, then ensure container lid is installed securely.
CAUTION:
I For ECM models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pressure Releaseº,
ªBASIC SERVICE PROCEDUREº).
I Do not disconnect any fuel line unless absolutely necessary.
I Plug hose and pipe openings to prevent entry of dust or dirt.
I Always replace top lid seal and hose clamps with new ones.
I Do not kink or twist hoses and tubes during installation.
I Do not tighten hose clamps excessively because this could cause damage to the hose.
I Ensure fuel check valve is installed in the correct orientation.
I Refer to EC section (ªFUEL CHECK VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
I After installation, run engine and check for fuel leaks at connections.
Fuel Pump and Gauge
REMOVAL
Petrol engine
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the luggage com- partment carpet.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during installa-
tion.
5. Remove the fuel gauge assembly and disconnect tubes and connector.

CAUTION:
IBe careful not to drop or damage catalytic converter.
I Never wet catalytic converter with water, oil, etc.
I Always replace exhaust gaskets with new ones when reas-
sembling.
If gasket is left on flange surface, scrape off complete as
shown at left.
I With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
I After installation, but before fully tightening exhaust joints,
check to ensure that mounting brackets and mounting
insulators are free from undue stress. If any of the above
parts are not installed properly, excessive noise or vibra-
tion may be transmitted to the vehicle body.
