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 the Fuel
Delivery System - Repair Procedures - "Release Residual Pressure in
Fuel Line").
When removing the fuel pump relay, 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 “Intake And Exhaust System” in EM group).
4.
Disconnect the fuel pressure regulator 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 “Purge Control Solenoid Valve” in this group).
(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.
Installation is reverse of removal.
Use the special service tool [SST No.: 09314-3Q100] to install the high pressure fuel pipe.
