Remove the upper fuel injection fuel rail noise shield (1).
If equipped, cut the tie strap (1).
- Disconnect the fuel pressure sensor electrical connector (2).
- Remove the fuel pressure sensor (3).
- Disconnect the engine wiring harness from the fuel injector wiring harnesses as necessary.
- Remove the fuel injector wiring harnesses from any brackets as necessary.
Remove the bank 2 fuel injection fuel rail fasteners (1).
Remove the bank 1 fuel injection fuel rail fasteners (1) for clearance purposes.
