Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on the electrical components.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion with a mixture of baking soda and water.
- Reconnect the terminals after cleaning.
Test Battery:
- Use a multimeter to check voltage. If it's below 12.4 volts, consider replacing the battery.
- If replacing, ensure the new battery matches the specifications (CCA rating, dimensions).
Install New Battery:
- Place the new battery in the tray and secure it with the hold-down clamp.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Remove Starter Motor:
- Disconnect battery terminals again.
- Remove any components obstructing starter access (like the air intake duct).
- Unscrew the starter motor mounting bolts and take out the starter.
Test Starter:
- Connect the starter directly to the battery with jumper cables to verify operation.
Install New Starter (if necessary):
- Position the new starter in place and secure it with mounting bolts.
- Reconnect wiring harness to the starter.

4. Fuel System Inspection

Check Fuel Pump:
- Locate the fuel pump fuse in the fuse box and inspect it.
- If intact, connect a fuel pressure gauge to the fuel rail to check fuel pressure.
- If pressure is low, consider replacing the fuel pump.
Replace Fuel Filter (if applicable):
- Locate the fuel filter; disconnect fuel lines and replace it with a new one.
