Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and in park or neutral with the parking brake engaged.
Disconnect the battery to ensure safety during repair.

2. Battery and Connections

Sub-steps:
1. Inspect the battery terminals for corrosion. Clean if necessary using a wire brush.
2. Use a multimeter to check battery voltage; it should be above 12.4 volts.
3. If the battery is weak, replace it with a fully charged battery.

3. Fuel System Inspection

Sub-steps:
1. Locate the fuel pump relay in the fuse box and check for functionality.
2. Remove the fuel pump access panel (if applicable) and test the fuel pump with a 12V power supply to ensure it operates.
3. If the fuel pump is faulty, replace it with a new unit.

4. Ignition System Repair

Sub-steps:
1. Remove the spark plug wires and inspect for wear or damage. Replace if necessary.
2. Remove the spark plugs and inspect for fouling or wear. Replace as needed with OEM parts.
3. Test the ignition coils with a multimeter to ensure they are within resistance specs.

5. Reassembly and Testing

Sub-steps:
1. Reconnect all components and ensure everything is secure.
2. Reconnect the battery.
3. Attempt to start the engine and monitor for proper operation.
