Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Disconnect the battery to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Sub-step 1: Remove the battery terminal bolts (10mm socket) and disconnect the negative terminal first, followed by the positive terminal.
Sub-step 2: Test the battery with a multimeter; it should read at least 12.6 volts when fully charged.
Sub-step 3: If the battery is weak or faulty, replace it with a new battery, ensuring it matches the specifications of the vehicle.

3. Fuel System Check

Sub-step 1: Locate the fuel pump fuse and relay in the fuse box; check for any blown fuses and replace as necessary.
Sub-step 2: Use the OBD-II scanner to check for fuel system-related DTCs.
Sub-step 3: If the fuel pump is not functioning, replace it by removing the fuel tank if necessary. Ensure proper sealing and connection when reinstalling.

4. Ignition System Inspection

Sub-step 1: Remove the spark plug wires and inspect them for damage; replace any that show wear.
Sub-step 2: Remove the spark plugs using a spark plug socket and inspect their condition. Replace if they are fouled or worn.
Sub-step 3: Test the ignition coils with a multimeter to ensure they are within specifications. Replace any faulty coils.

5. Starter Motor Testing and Replacement

Sub-step 1: Locate the starter motor and inspect the wiring for any damage.
Sub-step 2: Test the starter motor directly by applying voltage to its terminals with the multimeter.
Sub-step 3: If the starter does not engage, replace it with a new starter motor, ensuring proper torque specifications for mounting bolts (typically 20-30 ft-lbs).
