4. Reassemble the housing securely.

4. Check and Repair Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Start the engine and check the fuel pressure against manufacturer specifications.
3. If pressure is low, inspect the fuel pump and replace if necessary.
4. Inspect fuel injectors for clogs and clean or replace as needed.

5. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Visually inspect engine mounts for cracks or wear.
2. If damaged, lift the engine slightly using a jack with a block of wood for support.
