Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative battery terminal followed by the positive terminal.
2. Remove the battery from the vehicle using a socket set.
3. Test the battery with a multimeter; if the voltage is below 12.4V, replace the battery.
4. Install the new battery, connecting the positive terminal first, then the negative terminal.
Tools Required: Socket set, multimeter.

3. Fuel System Check and Repair

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Reinstall the fuse and connect a fuel pressure gauge to the fuel rail.
3. Turn the ignition to the "ON" position (do not start) and check the pressure; it should meet manufacturer specifications (consult service manual).
4. If the pressure is low, inspect and replace the fuel pump or fuel filter if necessary.
Tools Required: Fuel pressure gauge, socket set.

4. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs using a socket set.
2. Inspect the spark plugs for wear or deposits; replace if damaged.
3. Test the ignition coils with a multimeter for proper resistance.
4. Replace any faulty ignition coils.
Tools Required: Socket set, multimeter.
