Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts and ensure safety.
Allow the engine to cool if it has been running recently.

2. Battery Inspection and Replacement

Remove the battery terminals (negative first, then positive).
Clean battery terminals and cable ends with a wire brush.
Test the battery with a load tester; replace if it fails to hold a charge.
Install a new battery if necessary, ensuring correct terminal orientation.
Reconnect the battery terminals (positive first, then negative).

3. Starter Motor Check

Remove any components obstructing access to the starter motor.
Disconnect the wiring harness from the starter.
Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
If no voltage is present, check ignition switch and wiring. Replace starter if it is faulty.

4. Fuel System Inspection

Check the fuel pump relay and fuse in the fuse box for continuity and replace if necessary.
Test the fuel pump for proper operation using a fuel pressure gauge; replace if pressure is below specifications.
Inspect fuel lines and filter for blockages, replacing as needed.
