• Reply with: “I have an access cover” or “No access cover”.
• Reply with whether you have a scan tool that can command a fuel pump prime: Yes or No.

Step 2: Stop here to avoid wrong disassembly

• Once you answer the two checks above, I’ll give you the exact Pacifica-specific steps, including the correct access method, connector handling, and reassembly torque specs.
