Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Wear safety goggles and gloves.

2. Battery Inspection

Disconnect the negative terminal of the battery.
Clean any corrosion from battery terminals using a wire brush.
Tighten any loose connections and reconnect the battery.

3. Fuel System Check

Locate the fuel pump relay and check it for proper operation.
If the pump is inoperative, replace the fuel pump.
If the fuel pressure is low, replace the fuel filter if clogged or the fuel pump if faulty.

4. Ignition System Repair

Remove the spark plugs using a socket wrench and inspect for wear or deposits.
Replace worn spark plugs with new ones, ensuring the gap is set to manufacturer specifications.
Inspect the ignition coils for signs of damage; replace any faulty coils.
