Solution

1. Preparation

Gather necessary tools and parts. Ensure you have a fully charged battery or jump starter.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure battery voltage.
- If below 12.4 volts, charge or replace the battery.
Clean Battery Terminals
- Remove the battery terminals (negative first, then positive).
- Clean terminals with a wire brush and apply a corrosion inhibitor.
Reconnect Battery
- Reconnect the positive terminal first, then the negative.

3. Starter Motor Testing

Bypass Starter
- Locate the starter motor under the vehicle.
- Use a jumper wire to connect the positive terminal on the starter with the battery. If it cranks, the starter is functional.
Replace Starter if Necessary
- If it does not crank, remove the starter motor using a socket set.
- Install a new starter motor and torque mounting bolts to manufacturer's specifications.

4. Ignition System Check

Inspect Ignition Switch
- Remove the steering column cover to access the ignition switch.
- Test continuity with a multimeter; replace if defective.

5. Fuel System Verification

Check Fuel Pump Operation
- Turn the ignition key to "ON" without starting; listen for the fuel pump.
- If no sound, inspect fuel pump relay and replace as needed.
