Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from battery terminals using a wire brush.
- Tighten any loose connections.
Replace Battery (if necessary):
- Remove the negative terminal first, then the positive terminal.
- Unbolt and remove the battery from its tray.
- Install the new battery and connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

Remove Starter Motor:
- Disconnect battery again.
- Locate the starter motor, usually near the bottom of the engine.
- Remove the electrical connections and mounting bolts.
- Carefully pull the starter motor out.
Test Starter:
- Use a multimeter to check resistance; replace if necessary.

4. Fuel System Inspection

Check Fuel Pump:
- Locate the fuel pump relay and test for proper operation.
- If faulty, replace the relay.
Inspect Fuel Lines:
- Look for leaks or blockages in fuel lines.
Replace Fuel Filter (if applicable):
- Remove the old fuel filter and install a new one according to manufacturer specifications.

5. Spark Plug Replacement

Remove Old Spark Plugs:
- Use a spark plug socket to remove each spark plug.
Inspect and Replace:
- Check the gap on new spark plugs and adjust as necessary.
- Install new spark plugs and torque them to manufacturer specifications.
