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 “Release Residual Pressure in Fuel Line” in this
group).
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 intake manifold (Refer to "Intake
And Exhaust System" in EM group). |
4. |
