Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is in park (automatic) or neutral (manual).
  • Disconnect the battery to prevent electrical shorts.
2. Battery Inspection and Replacement
  • Inspect Battery:
    • Check for corrosion on battery terminals and clean if necessary.
    • Ensure terminals are tightly secured.
  • Replace Battery (if necessary):
    • Remove the negative terminal first, followed by the positive terminal.
    • Remove the battery from the tray.
    • Install the new battery by connecting the positive terminal first, then the negative.
3. Starter Motor Inspection and Replacement
  • Inspect Starter Motor:
    • Locate the starter motor, usually near the bottom of the engine near the transmission.
    • Check the wiring and connectors for damage or looseness.
  • Replace Starter Motor (if necessary):
    • Disconnect battery (if not already done).
    • Remove the electrical connections from the starter.
    • Unbolt the starter from its mounting (usually requires a socket set).
    • Install the new starter in reverse order of removal, ensuring all connections are secure.
4. Relay and Fuse Checks
  • Starter Relay:
    • Locate the starter relay in the fuse box.
    • Replace with a new relay or swap with a similar relay to test functionality.
  • Fuses:
    • Inspect and replace any blown fuses related to the ignition or starter system.
