Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety during the process.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set, wire brush (for terminals), battery terminal cleaner.
Check the battery voltage using a multimeter; it should read around 12.6 volts when fully charged.
If voltage is low, charge the battery and retest. If it fails to hold a charge, replace the battery.
Clean the battery terminals and cables with a wire brush and terminal cleaner to remove corrosion.
Reconnect the battery terminals securely.

3. Starter Motor Inspection and Replacement

Tools Required: Socket set, multimeter, torque wrench.
Locate the starter motor (typically near the engine block).
Disconnect the wiring harness and battery cable from the starter.
Test the starter motor by applying direct power from the battery; it should engage and spin.
If the starter is faulty, remove the old starter by unbolting it and replace it with a new unit.
Torque the bolts to manufacturer specifications and reconnect the wiring.

4. Fuel System Check

Tools Required: Fuel pressure gauge, safety goggles, rags.
Attach a fuel pressure gauge to the fuel rail test port.
Turn the ignition key to the "ON" position (do not start) and observe the fuel pressure reading; it should meet manufacturer specifications.
If pressure is low, inspect the fuel pump and fuel filter for clogs or failure. Replace components as needed.

5. Ignition System Inspection

Tools Required: Spark plug socket, torque wrench, ignition coil puller.
Remove the spark plugs using a spark plug socket and inspect them for wear or fouling.
Replace any damaged spark plugs with new ones, torquing them to the specified value.
Check the ignition coils for proper function; replace if any are defective.
