Solution

1. Preparation

Gather all necessary tools and parts.
Ensure you are working in a well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-step 1: Remove the battery cover if necessary using a socket set.
Sub-step 2: Disconnect the positive terminal first, followed by the negative terminal.
Sub-step 3: Remove the battery from the vehicle and inspect for physical damage or swelling.
Sub-step 4: If replacing the battery, install the new battery by connecting the positive terminal first, followed by the negative terminal.
Sub-step 5: Reinstall the battery cover.

3. Starter Motor Inspection and Replacement

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Remove any covers or shields obstructing access.
Sub-step 3: Disconnect the electrical connectors from the starter motor.
Sub-step 4: Remove the mounting bolts using a socket set and carefully take out the starter.
Sub-step 5: Install the new starter by reversing the removal steps, ensuring all connections are secure.

4. Fuel System Check

Sub-step 1: Locate the fuel pressure test port on the fuel rail.
Sub-step 2: Attach a fuel pressure gauge to the test port and turn the ignition to the "ON" position without starting the engine.
Sub-step 3: Record the fuel pressure reading; it should meet the manufacturer's specifications.
Sub-step 4: If pressure is low, inspect the fuel pump and replace if necessary.
