Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion using a wire brush.
- Tighten any loose connections.
Test Battery:
- If the voltage is below 12.4 volts, replace the battery.
- Use a battery tester for a load test if available.
Replace Battery (if necessary):
- Remove the old battery carefully.
- Install the new battery in reverse order of removal.
- Reconnect the negative battery cable.

3. Starter Motor Diagnosis and Replacement

Test Starter Motor Functionality:
- If clicking occurs, remove the starter motor for inspection.
- Test the starter with direct power from a battery.
Replace Starter Motor (if faulty):
- Remove the electrical connections and mounting bolts.
- Install the new starter motor and replace bolts to manufacturer specifications (typically 15-25 ft-lbs).
- Reconnect electrical connections.

4. Fuel System Check

Inspect Fuel Pump:
- If no noise is heard, check the fuel pump fuse and relay.
- Replace if faulty and ensure the fuel pump is operational.
Replace Fuel Pump (if necessary):
- Remove the fuel pump assembly from the tank per manufacturer instructions.
