Kia Optima: 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 “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 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.:
