Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Battery and Charging System

Sub-steps:
1. Reconnect the battery and use a multimeter to measure the battery voltage; it should be around 12.6 volts when fully charged.
2. Start the engine and measure the voltage again; it should read between 13.7 to 14.7 volts indicating proper charging.
3. If the voltage is low, clean the battery terminals and tighten the connections. Replace the battery if it fails to hold a charge.

3. Inspect Fuel Delivery System

Sub-steps:
1. Check the fuel pump operation by listening for a humming sound when the ignition is turned on.
2. If no sound is heard, test the fuel pump relay and replace if faulty.
3. Inspect the fuel filter for clogs and replace if necessary.
4. Use a fuel pressure gauge to ensure the fuel pressure is within specifications (consult the service manual for exact values).

4. Evaluate Ignition System

Sub-steps:
1. Remove and inspect spark plugs for wear or fouling; replace if necessary.
2. Test ignition coils with a multimeter for proper resistance; replace any that are out of specifications.
3. Check the ignition switch for proper functionality by testing for continuity when in the "on" position.

5. Wiring and Connections Inspection

Sub-steps:
1. Visually inspect the engine wiring harness for any frayed or damaged wires.
2. Clean and secure all connectors to ensure a good electrical connection.
3. Use a multimeter to check for continuity in the wiring to the ignition and fuel systems.
