Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, fuel pressure gauge, and safety glasses.
Ensure the vehicle is in a well-ventilated area and the engine is cool.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion with a wire brush.
Test Battery:
- Use a multimeter to check the voltage. If it is below 12.4 volts, consider charging or replacing it.
Replace Battery (if necessary):
- Disconnect the old battery and install a new one, ensuring correct polarity.
- Tighten terminals to manufacturer specifications (usually around 10-15 Nm).

3. Starter Motor Testing

Remove Starter Motor:
- Disconnect the battery.
- Remove electrical connectors from the starter.
- Unbolt the starter from the engine using a socket set.
Test Starter:
- Connect starter motor directly to a battery using jumper cables.
- If it does not engage, replace the starter motor.

4. Fuel System Check

Inspect Fuel Pump:
- Locate the fuel pump fuse in the fuse box and inspect it for continuity.
- Use a fuel pressure gauge to check fuel pressure at the fuel rail. It should be within the manufacturer’s specifications (typically around 40-50 psi).
Replace Fuel Pump (if necessary):
- If fuel pressure is low, remove the fuel pump from the fuel tank (follow manufacturer guidelines).
- Install a new fuel pump and reassemble all components.
