Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical issues.
• Ensure the vehicle is on a flat surface and securely elevated if needed.

2. Remove Fuel Injectors

• Tools Required: Socket set, ratchet, torque wrench, fuel line disconnect tool.
• Relieve fuel system pressure: Remove the fuel pump fuse and start the engine until it stalls.
