Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative battery terminal to ensure safety.
2. Clean the battery terminals and cable connections using a wire brush and a mixture of baking soda and water.
3. Test the battery with a multimeter. If the voltage is below 12.6 volts, replace the battery.
4. Reconnect the battery terminals securely.

3. Fuel System Check

Sub-steps:
1. Turn the ignition to the "ON" position (without starting) to prime the fuel pump.
2. Check the fuel pressure at the fuel rail using a fuel pressure gauge. It should be within the manufacturer’s specifications (typically 30-50 PSI).
3. If the pressure is low, inspect the fuel filter and replace it if clogged. Check the fuel pump operation.

4. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs using a socket set and inspect for wear or fouling.
2. Replace any faulty spark plugs with OEM or equivalent parts.
3. Check the ignition coils for proper operation and replace any that are malfunctioning.

5. Starter Motor Assessment

Sub-steps:
1. Remove the starter motor connections and inspect for corrosion or damage.
2. Test the starter motor by applying direct battery voltage; if it does not engage, replace the starter.
3. Reinstall the starter motor and reconnect all electrical connections.
