Solution

1. Preparation

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

2. Inspect and Clean Battery Connections

Remove the negative (-) terminal first, then the positive (+) terminal.
Clean any corrosion from the battery terminals and cable connectors using a wire brush.
Reconnect the battery terminals, ensuring a tight fit.

3. Test and Replace Battery (if necessary)

If the battery voltage is below 12.4 volts, charge or replace it.
To replace, remove the battery hold-down bracket and lift the battery out.
Install the new battery, ensuring the positive terminal is connected first, followed by the negative terminal.

4. Check Starter Motor

Locate the starter motor; generally found near the engine block.
Disconnect the electrical connector and the battery cable from the starter.
Using a multimeter, test for power at the starter when the ignition is turned to the "start" position.
If there is no power, the ignition switch may need replacing.

5. Inspect Fuel Delivery System

Check the fuel pump fuse and relay in the fuse box.
If the fuse is blown, replace it and retest.
If the fuel pump is faulty, replace it by removing the rear seat (if applicable) to access the fuel pump module.
