Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean any corrosion from the battery terminals using a wire brush.
2. If the battery voltage is low, replace the battery with a compatible model (typically a Group 65 for Ford Explorers).
3. Reconnect the terminals, ensuring a tight fit.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Remove the starter motor from the vehicle by disconnecting the electrical connections and unbolting it.
2. Test the starter by connecting it directly to a battery to see if it engages.
3. If it fails, replace it with a new starter motor and reinstall it.

4. Fuel System Check

Sub-steps:
1. Check the fuel pump relay and replace if defective.
2. Inspect the fuel pump and replace if it’s not functioning. Ensure to relieve fuel pressure before removal.
3. Reconnect all components and check for leaks.
