Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a safe, dry location.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion using a mixture of baking soda and water with a wire brush.
- Check the battery's age; if over 3-5 years, consider replacing it.
Replace Battery (if necessary):
- Remove the old battery and replace it with a new battery of the same specifications.
- Reconnect the terminals (positive first, then negative).

3. Fuel System Check

Inspect Fuel System:
- Ensure there is adequate fuel in the tank.
- Listen for the fuel pump priming (a quiet whir sound) when the ignition is turned on.
- If not audible, check the fuel pump relay and fuses.
Replace Fuel Filter (if applicable):
- Disconnect the fuel lines using appropriate line wrenches.
- Replace the fuel filter and reconnect lines securely.

4. Ignition System Check

Inspect Spark Plugs:
- Remove spark plugs using a socket wrench.
- Check for wear, carbon buildup, or damage; replace if necessary.
Test Ignition Coils:
- Use a multimeter to check the resistance of each ignition coil.
- Replace any faulty coils as per the manufacturer’s specifications.
