Warning

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.

Fuel Pressure Test (Low pressuresystem)

Release the residual pressure in fuel line. (Refer to the Fuel Delivery System - Inspection - "Release Residual Pressure in Fuel Line"). Warning When removing the fuel pump fuse, a Diagnostic Trouble Code (DTC) may occur. De
