Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Battery Inspection and Replacement

Sub-steps:
1. Use a multimeter to check the battery voltage; it should be above 12.4 volts.
2. Clean battery terminals and cables to ensure good connections.
3. If the battery is found to be weak, replace it with a new battery of the same specifications.

Tools Required: Multimeter, wrench set

3. Fuel System Check

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "on" position (without starting) and check for the specified fuel pressure (consult the service manual for specifications).
3. If pressure is low, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
4. Replace the fuel filter if clogged and ensure the fuel pump is functioning properly.

Tools Required: Fuel pressure gauge, socket set

4. Starter Motor and Ignition System Repair

Sub-steps:
1. Remove the starter motor from the vehicle by unbolting it from the transmission.
2. Inspect the starter motor for wear and test it with a bench test; replace it if faulty.
3. Check the ignition coils and spark plugs; replace any that show signs of damage or excessive wear.

Tools Required: Socket set, screwdriver set

5. Air Intake Inspection

Sub-steps:
1. Remove the air intake duct and inspect for debris or obstructions in the air filter.
2. Replace the air filter if it is dirty or clogged.
3. Reassemble the intake system securely.

Tools Required: Screwdriver set, pliers
