Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuel pressure gauge, jumper cables.
Ensure the vehicle is parked in a well-ventilated area and allow the engine to cool if recently operated.

2. Battery Replacement

Sub-steps:
1. Disconnect the negative (-) battery terminal, followed by the positive (+) terminal.
2. Remove any battery hold-down brackets using the socket set.
3. Carefully lift the battery out of the tray.
4. Install the new battery in reverse order: place it in the tray, secure brackets, and connect the positive terminal first, followed by the negative terminal.
Safety Warnings: Wear gloves and safety goggles to protect against battery acid.

3. Fuel System Check

Sub-steps:
1. Locate the fuel rail and connect the fuel pressure gauge to the service port.
2. Turn the ignition to the "ON" position (do not start) and check the pressure; it should be within the specifications listed in the service manual.
3. If pressure is low, inspect the fuel pump and relay for function and replace if necessary.
Safety Warnings: Relieve fuel system pressure before disconnecting any fuel lines to avoid fuel spray.

4. Starter Inspection

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the starter motor from its mountings using the socket set.
3. Inspect the starter solenoid and connections for wear or corrosion.
4. Test the starter with a multimeter, ensuring it engages properly when powered.
5. Replace the starter if it fails testing.
Safety Warnings: Ensure the vehicle is in park/neutral with the parking brake engaged.
