Fuel Rail Assembly

Removal Procedure

NOTE:

f

Do not attempt to remove the fuel inlet fitting on the
fuel rail.  It is staked in place.  Removing the fuel inlet
fitting will result in damage to the fuel rail or the
internal O-ring seal.

f

Use care when removing the fuel rail assembly in
order to prevent damage to the injector electrical
connector terminals and the injector spray tips.

f

Fittings should be capped and holes plugged during
servicing to prevent dirt and other contaminants from
entering open lines and passages.

IMPORTANT:

An eight-digit identification number is

stamped on the side of the fuel rail.  Refer to this number
when you service the fuel rail or when a replacement part
is required.

TS24022

Before removal, the fuel rail assembly may be cleaned
with a spray type engine cleaner.  Follow the spray
package instructions.  Do not immerse the fuel rails in
liquid cleaning solvent.

1. Depressurize the fuel system. Refer to Fuel Pressure

Relief Procedure in this Section.

2. Disconnect the negative battery cable.
3. Remove the engine cover.
4. Disconnect the accelerator pedal cable from throttle

body and cable bracket.

5. Disconnect the connectors from manifold absolute

pressure sensor, solenoid valve, electric vacuum
sensing valve.

6. Disconnect the vacuum hose on canister VSV and

positive crankcase ventilation hose.

7. Remove the common chamber Refer to the common

chamber in Engine Mechanical.
1. Lift up carefully on the fuel injectors. Do not

separate the fuel injectors from the fuel rail.

6E2–476

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

2. If an injector becomes separated from the fuel

rail, the infector O-ring seals and the retainer clip
must be replaced.

3. Drain residual fuel into an approved container.

014RW106

8. If removal of the fuel pressure regulator is necessary,

refer to 

 Fuel Pressure Regulator.

9. If removal of the fuel injectors is necessary, refer to

Fuel Injectors.

Installation Procedure

1. If the fuel injectors were removed, install them.  Refer

to 

Fuel Injectors.

2. If the fuel pressure regulator was removed, install it.

Refer to 

Fuel Pressure Regulator.

3. Install the common chamber.Refer to common

chamber in engine Mechanical.

014RW106

4. Connect the vacuum hose on Canister VSV and

positive crankcase ventilation hose.

5. Connect the connectors to manifold absolute

pressure sensor, solenoid valve, electric vacuum
sensing valve.

6. Connect the accelerator pedal cable to throttle body

and cable bracket.

7. Install the engine cover.
8. Connect the negative battery cable.
9. Crank the engine until it starts.  Cranking the engine

may take longer than usual due to trapped air in the
fuel rail and in the injectors.

Fuel Tank

Removal Procedure

Refer to

Fuel Tank In Fuel Pump Relay.

014RW134

Throttle Body (TB)

Removal Procedure

1. Disconnect the negative battery cable.
2. Drain the cooling system.  Refer to 

Cooling System.

3. Remove the accelerator cable assembly.  Refer to

Accelerator Cable in Engine Speed Control System..

4. Disconnect the electrical connectors:

f

Throttle position (TP) sensor.

f

Idle air control (IAC) solenoid.

6E2–477

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

f

Intake air temperature (IAT) sensor.  Refer to 

Intake

Air Temperature Sensor.

035RW023

5. Disconnect the vacuum hose below the air horn.
6. Remove the intake air duct clamp.
7. Disconnect the intake air duct.
8. Disconnect the coolant lines from the throttle body.
9. Remove the bolts from the common chamber.

10. Remove the throttle body from the common chamber.

11. Remove the gasket from the upper intake manifold.

035RW024

12. Remove the IAC.  Refer to 

Idle Air Control (IAC)

Solenoid.

13. Remove the TP sensor.  Refer to 

Throttle Position

(TP) Sensor.

Inspection Procedure

NOTE: Do not use solvent of any type when you clean the
gasket surfaces on the intake manifold and the throttle
body assembly.  The gasket surfaces and the throttle
body assembly may be damaged as a result.

f

If the throttle body gasket needs to be replaced,
remove any gasket material that may be stuck to the
mating surfaces of the manifold.

f

Do not leave any scratches in the aluminum casting.

Installation Procedure

1. Install the TP sensor.  Refer to 

Throttle Position (TP)

Sensor.

2. Install the IAC.  Refer to 

Idle Air Control (IAC)

Solenoid.

3. Install the gasket on the common chamber.
4. Install the throttle body on the common chamber.
5. Secure the gasket and the throttle body with the four

bolts.

f

The vacuum lines must be properly routed under
the throttle body before tightening the mounting
bolts.

Tighten

f

Tighten the throttle body mounting bolts to 24
N·m (17 lb ft.).

035RW024

6. Install the coolant lines.
7. Connect all the vacuum lines.
8. Install the intake air duct.
9. Tighten the intake air duct clamp.

the rocker cover.

014RW108

4. Remove the coil module and the spark plug boot from

the spark plug.

f

Twist the coil module while pulling it straight up.

014RW091

5. Use the spark plug socket in order to remove the

spark plug from the engine.

Spark Plug Gap Check

f

Check the gap of all spark plugs before installation.

f

Use a round wire feeler gauge to ensure an accurate
check.

f

Plugs installed with the wrong gap can cause poor
engine performance and excessive emissions.

Installation Procedure

NOTE: The plug must thread smoothly into the cylinder
head and be fully seated.  Use a thread chaser if
necessary to clean the threads in the cylinder head.
Cross-threading or failure to fully seat the spark plug can
cause plug overheating, exhaust blow-by gases, or
thread damage.  Do not overtighten the spark plugs.  Over
tightening can cause aluminum threads to strip.

1. Install the spark plug in the engine.  Use the

appropriate spark plug socket.

Tighten

f

Tighten the spark plug to 18 N·m (13 lb ft.).
