Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Inspect Battery: Clean terminals with a wire brush if corrosion is present.
Replace Battery: If the battery voltage is below 12.4 volts, replace it with a new one.
- Disconnect negative terminal first, then positive.
- Remove the battery hold-down clamp and lift the battery out.
- Install the new battery by reversing the removal steps.
- Connect positive terminal first, then negative.

3. Starter Motor Replacement

Remove Starter:
- Disconnect the negative battery terminal for safety.
- Remove any components obstructing access to the starter (e.g., air intake duct).
- Unbolt starter mounting bolts and disconnect wiring harness.
Install New Starter:
- Position the new starter in place and secure it with bolts.
- Reconnect the wiring harness.
- Reinstall any components removed for access.

4. Fuel System Check

Check Fuel Pump: If the fuel pump is suspected, test it by:
- Checking the fuel pump fuse and relay; replace if defective.
- If necessary, drop the fuel tank to access the pump for replacement.
- Install the new fuel pump according to manufacturer instructions.

5. Ignition System Repair

Inspect and Replace Components:
- Remove the ignition coil and spark plugs for inspection.
- Replace any damaged components as necessary; use OEM parts for best compatibility.
