Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair Procedures: 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.
- Turn the ignition switch OFF and disconnect the battery negative (-) cable.
- Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "RELEASE RESIDUAL PRESSURE IN FUEL LINE ")
CAUTION:- 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.
- Disconnect the fuel feed tube quick-connector (A) using a clip tool.
- Disconnect the fuel pressure control valve-connector (B).NOTE:
- Open the clamp cover (B) before disconnect the quick connector. (If the clip is applied)
CAUTION:- When removing the quick-connector with the clip removing tool (A), be careful not to damage the plastic clip (B).
