Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuel pressure gauge, basic hand tools.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before working on any components.

2. Battery Replacement (if necessary)

Remove the negative battery terminal followed by the positive terminal.
Unbolt the battery hold-down bracket and remove the battery from the tray.
Install the new battery, ensuring it is secured with the hold-down bracket.
Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Replacement (if necessary)

Disconnect the negative battery terminal.
Remove any components obstructing access to the starter motor (e.g., air intake duct).
Unplug the electrical connectors from the starter motor.
Remove the mounting bolts securing the starter motor to the engine.
Install the new starter motor by reversing the steps, ensuring bolts are torqued to manufacturer specifications (typically 10-15 lb-ft).

4. Fuel Pump Replacement (if necessary)

Relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the negative battery terminal.
Remove the fuel tank (if necessary) or access panel to reach the fuel pump.
Disconnect fuel lines and electrical connectors from the fuel pump.
Remove the fuel pump from the tank and install the new fuel pump, ensuring all connections are secure and leak-free.
