Solution

1. Preparation

Gather tools and parts.
Make sure the vehicle is parked on a level surface.
Disconnect the battery to ensure safety while working on electrical components.

2. Battery Inspection and Replacement (if necessary)

Sub-steps:
1. Remove the negative terminal followed by the positive terminal from the battery.
2. Clean any corrosion from the terminals using a wire brush.
3. If the battery is weak (below 12.4 volts), replace with a new battery of the same size and specifications.
4. Connect the new battery by first attaching the positive terminal, followed by the negative terminal.
5. Ensure terminals are tightened securely.

3. Fuel System Inspection

Sub-steps:
1. Locate the fuel pump relay and check it for proper function.
2. If the fuel pump is not functioning, replace it. To do this, remove the fuel tank access panel, disconnect the fuel lines, and unscrew the pump from the tank.
3. Install the new fuel pump and reconnect all lines and electrical connectors.

4. Spark Plug Inspection and Replacement (if necessary)

Sub-steps:
1. Remove spark plug wires or ignition coils carefully.
2. Use a socket wrench to remove the spark plugs.
3. Inspect plugs for wear, deposits, or damage; replace if necessary.
4. Install new spark plugs, ensuring they are gapped correctly according to vehicle specifications.
5. Reattach spark plug wires or ignition coils securely.
