Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, wrench set, battery terminal cleaner, and safety goggles.
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 first, followed by the positive (+) terminal.
2. Clean any corrosion from the battery terminals using a battery terminal cleaner.
3. Reconnect the terminals and retry starting the vehicle; if it still struggles, proceed to battery replacement.
4. If replacement is needed, remove the old battery and install a new one that meets OEM specifications (check the owner's manual).
5. Reconnect the terminals, ensuring that the positive terminal is connected first.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor and inspect the wiring and connections for signs of damage.
2. Perform a bench test on the starter motor to confirm functionality. If it fails, replace the starter motor.
3. Install the new starter motor and ensure all connections are secure.

4. Fuel System Inspection

Sub-steps:
1. Check the fuel pump relay and fuses for functionality.
2. Use a fuel pressure gauge to measure the fuel pressure; it should meet manufacturer specifications.
3. If pressure is low, replace the fuel filter and inspect the fuel pump for proper operation.

5. Ignition System Maintenance

Sub-steps:
1. Remove and inspect spark plugs for wear; replace if necessary.
2. Check ignition coils for proper operation; replace any faulty coils.
3. Ensure all electrical connections in the ignition system are clean and secure.
