Removal
In case of removing the high pressure fuel pump, high pressure
fuel pipe, delivery pipe, and injector, there may be injury caused by
leakage of the high pressure fuel. So don’t do any repair work right
after engine stops.
|
1. |
Turn the ignition switch OFF and disconnect the battery negative
(-) cable.
|
2. |
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - “Release Residual Pressure in
Fuel Line”)
When removing the fuel pump fuse, a Diagnostic Trouble
Code (DTC) may occur.
Delete the code with the GDS after completion of “Release
Residual Pressure in Fuel Line” work.
|
|
3. |
Remove the air cleaner and the air intake hose
(Refer to Engine Mechanical System - “Intake And Exhaust System”)
|
4. |
Disconnect the fuel pressure control valve connector (A).
|
5. |
Remove the ignition coil (B).

|
6. |
Disconnect the fuel feed tube quick-connector (A).
|
7. |
Remove the high pressure fuel pipe.
(1) |
Remove the installation nut (B) from the high pressure
fuel pump with the special service tool [SST No.: 09314-3Q100]

|
(2) |
Remove the installation nut (C) from the delivery pipe
with the special service tool [SST No.: 09314-3Q100]
|
(3) |
Remove the purge control solenoid valve.
(Refer to Engine Control Systme - “PCSV”)
|
(4) |
Remove the function block (D), and then remove the high
pressure fuel pipe.
|
|
8. |
Remove the installation bolts (E), and then remove the high pressure
fuel pump from the cylinder head assembly.
Unscrew in turn the two bolts in small step (0.5 turns).
In case of fully unscrewing one of the two bolts with the other
bolt installed, the housing surface of the cylinder head may
be broken because of tension of the pump spring.

Installation
•
|
Be sure to check the low pressure fuel hose quick-connector
(A) is completely connected to the high pressure fuel pump until
a confirmation 'click' sound is heard.
|
•
|
Be sure to re-check the low pressure fuel hose is completely
connected to the high pressure fuel pump by pulling it after
connecting.
|
•
|
Be sure to install the high pressure fuel pipe (B) with
the specified torques.
|
•
|
Because fuel leak may cause fire, securely Inspect leakage
of all fuel line connection parts at engine start condition.
|
|

•
|
Before installing the high pressure fuel pump, position
the roller tappet in the lowest position by rotating the crankshaft.
Otherwise the installation bolts may be broken because of tension
of the pump spring.
|
|
•
|
Do not reuse the used bolt.
|
|
•
|
Do not reuse the used high pressure fuel pipe.
|
|
•
|
When tightening the installation bolts of the high pressure
fuel pump, tighten in turn the bolts in small step (0.5 turns)
after tightening them with hand-screwed torque.
|
|
•
|
Install the component with the specified torques.
|
•
|
First hand-tighten the fasteners fully until they are
not fastened any more in orderto have them inserted in place
and then completely tighten to the specified torque using a
torque wrench.
If not tightening the bolts or nuts in a straight line
with the mating bolt holes or fittings, it may cause a fuelleak
due to broken threads.
|
|
•
|
Note that internal damage may occur when the component
is dropped. In this case, use it after inspecting.
|
|
•
|
Apply engine oil to the O-ring (A) of the high pressure
fuel pump, the roller tappet (B), and the protrusion (C). Also
apply engine oil to the groove on the location where the protrusion
(C) is installed.
|
|

1. |
Install in the reverse order of removal.
Use the special service tool [SST No.: 09314-3Q100] to
install the high pressure fuel pipe.
