2. Battery Inspection and Replacement

Inspect the Battery:
- Check for corrosion on terminals. Clean with a wire brush if necessary.
- Tighten the connections.
Test the Battery:
- Use a multimeter to measure voltage. If below 12.4 volts, consider replacement.
Replace the Battery:
- Remove the old battery from the vehicle.
- Install the new battery, ensuring the connections are tight.
- Reconnect the negative terminal.

3. Starter Motor Testing and Replacement

Test the Starter:
- Using jumper cables, connect the starter motor directly to the battery to see if it engages.
Replace the Starter (if necessary):
- Disconnect battery and remove any components blocking the starter access.
- Unbolt the starter from its mounting and disconnect wiring.
- Install the new starter and reconnect wiring and bolts to specifications.

4. Fuel System Check

Inspect Fuel Pump:
