Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to avoid any electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Test the battery with a multimeter; replace if voltage is below 12.4V.
3. Clean the battery terminals with a wire brush to remove any corrosion.
4. Reinstall the battery, connecting the positive terminal first, followed by the negative.

3. Starter Motor Test and Replacement

Sub-steps:
1. Locate the starter motor and inspect its connections.
2. Use a multimeter to test voltage at the starter terminal while attempting to crank the engine.
3. If the starter motor fails to engage, remove it (unbolt and disconnect).
4. Replace with a new or refurbished starter motor, ensuring proper torque specifications (usually around 15-20 Nm).

4. Fuel System Inspection

Sub-steps:
1. Locate the fuel pressure test port; connect a fuel pressure gauge.
2. Start the engine and check for adequate fuel pressure (typically around 40-60 psi).
3. If pressure is low, inspect the fuel pump and filter for blockages or failures.
4. Replace the fuel filter if it shows signs of clogging.
