Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Replacement

Tools Required: Wrench set, battery terminal cleaner, safety goggles, gloves.
Remove the negative terminal (black) first and then the positive terminal (red).
Use a battery terminal cleaner to clean any corrosion on the terminals.
Remove the old battery by unfastening the hold-down clamp and lifting it out.
Install the new battery, securing it with the hold-down clamp.
Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection/Replacement

Tools Required: Socket set, wrench set, torque wrench.
Remove any components obstructing access to the starter motor (e.g., air intake duct).
Disconnect the electrical connectors from the starter.
Unbolt the starter motor from its mounting using a socket set.
Replace with a new starter motor, ensuring it is properly aligned.
Reconnect the electrical connectors and torque the bolts to the manufacturer's specifications.

4. Fuel System Check

Tools Required: Fuel pressure gauge, safety goggles, gloves.
Locate the fuel rail pressure test port and attach the fuel pressure gauge.
Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
If pressure is below specifications (usually around 40-50 psi), consider replacing the fuel pump.
To replace the fuel pump, access the fuel tank by removing the rear seats or access panel, disconnecting fuel lines, and unbolting the pump assembly.
