Solution

1. Preparation

Ensure the vehicle is in "Park" or "Neutral."
Disconnect the negative battery terminal to prevent electrical shock.
Gather tools: OBD-II scanner, multimeter, socket set, and wrenches.

2. Battery Inspection and Replacement

Sub-step 1: Reconnect the battery terminals; tighten them securely.
Sub-step 2: If the battery voltage is low, jump-start the vehicle or replace the battery if it cannot hold a charge.
- Tools Required: Battery terminal cleaner, battery replacement tools.

3. Starter Motor Replacement

Sub-step 1: Remove the starter motor by disconnecting the battery terminal, removing the electrical connections, and unbolting it from the mounting.
Sub-step 2: Install the new starter motor and ensure all connections are tight.
Sub-step 3: Reconnect the negative battery terminal.
- Torque Specification: Tighten starter bolts to manufacturer-recommended torque (typically around 25-30 ft-lbs).

4. Fuel System Check (if applicable)

Sub-step 1: If the starter engages but the engine does not start, check for fuel delivery.
Sub-step 2: Inspect the fuel pump fuse and relay; replace if necessary.
Sub-step 3: Test for fuel pressure at the fuel rail using a fuel pressure gauge.
- Tools Required: Fuel pressure gauge.
