  6. Install the other parts in the reverse order of removal.
  7. Add all the necessary fluids and check for leaks. Connect GDS. Check for codes, note, and clear. Recheck.
    NOTE:
    • Refill engine with engine oil.
    • Clean battery posts and cable terminals and assemble (12 Volt only).
    • Inspect for fuel leakage.
      • After assembling the fuel line, turn on the ignition switch so that the fuel pump runs for approximately two seconds and fuel line pressurizes.
      • Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
