Repair Procedures: Removal
WARNING:
When removing the high pressure fuel pump, high pressure fuel pipe, delivery pipe, and injector, injury may be caused by leakage of high pressure fuel. For this reason, do not attempt any repairing immediately after engine stops.
- Release the residual pressure in fuel line.
(Refer to the Fuel Delivery System - Repair Procedures - "RELEASE RESIDUAL PRESSURE IN FUEL LINE ")
- Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
- Remove the high pressure fuel pump foam (A).
- Disconnect the fuel pressure control valve connector (A) and fuel feed tube quick-connector (B).
- Remove the intake manifold.
(Refer to Engine Mechanical System - "INTAKE MANIFOLD ")
- Remove the high pressure fuel pipe.
(Refer to Fuel Delivery System - "FUEL LINE ")
- Remove the mounting bolts (A), and then remove the high pressure fuel pump (B) from the cylinder head assembly
High pressure fuel pump mounting bolt:
12.8 - 14.7 N.m (1.3 - 1.5 kgf.m, 9.4 - 10.9 lb.ft)
CAUTION: Unscrew in turns the two bolts in small steps (0.5 turns). When one of the two bolts is fully unscrewed while the other bolt still intact, the housing surface of the cylinder head may be broken due to tension of the pump spring.
