Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrench set.
Ensure the vehicle is in a safe, well-ventilated area and that the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Clean Terminals: Use a wire brush to clean any corrosion from the battery terminals.
Reconnect: Reattach the battery terminals securely and ensure no loose connections.

3. Starter Motor Testing

Remove Starter: Disconnect the wiring harness and remove the starter motor using a socket set. Note the mounting bolt locations.
Direct Voltage Test: Connect a jumper wire from the positive terminal of the battery to the starter motor terminal. Listen for engagement.
Replace if Faulty: If the starter does not engage, replace it with a new unit.

4. Check the Battery

Test Battery: If the battery is below 12.4 volts, charge it or replace it if it fails a load test.
Install New Battery: If replacing, ensure the new battery is compatible with the F-150.

5. Reassemble and Test

Reinstall the starter motor and reconnect all wiring.
Reconnect the negative battery terminal and test the vehicle by starting it.
