Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrenches.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the battery to ensure safety.

2. Battery Inspection and Replacement

Check Battery Voltage
- Connect the multimeter to the battery terminals.
- Ensure voltage is above 12.4 volts. If below, replace the battery.
Clean Battery Terminals
- Remove the battery cables (negative first, then positive).
- Clean any corrosion with a wire brush and baking soda solution.
- Reconnect the terminals securely.
Replace Battery (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Lift out the old battery and install the new one, ensuring it is seated correctly.
- Reattach the hold-down bracket and connect the terminals (positive first).

3. Starter Motor Inspection

Visual Inspection
- Locate the starter motor under the vehicle.
- Check for loose connections or visible damage.
Starter Function Test
- Have an assistant turn the ignition key while you tap the starter lightly with a hammer.
- If it starts, the starter may need replacement.
Replace Starter (if necessary)
- Disconnect battery again, then remove wiring from the starter.
- Unbolt the starter from its mount and replace it with a new unit.
- Reconnect battery and test the starter.

4. Fuel System Check

Check Fuel Pump Operation
- Locate the fuel pump fuse and relay; inspect for blown fuses.
- Listen for the fuel pump activating when turning the key to the ON position without starting.
Test Fuel Pressure
- Attach a fuel pressure gauge to the fuel rail.
- Ensure the pressure is within manufacturer specifications (check service manual).
Replace Fuel Pump (if necessary)
- If the pump is faulty, drain the fuel tank and remove it.
- Replace with a new fuel pump and ensure all connections are secure.
