Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Battery Inspection

Tools Required: Multimeter, socket set
Check the battery voltage using a multimeter; it should read around 12.6 volts.
If voltage is low, clean the battery terminals and cable connections. Tighten connections if necessary.
If the battery is faulty, replace it with a new one.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, screwdriver
Remove the fuel pump relay from the fuse box.
Using a fuel pressure gauge, connect it to the fuel rail and turn the ignition on (do not start the engine).
Check for the manufacturer’s specified fuel pressure; if low, inspect the fuel pump and fuel filter for blockages or failures.
Replace the fuel pump or filter if necessary.

4. Ignition System Inspection

Tools Required: Spark plug socket, multimeter
Remove the spark plugs and inspect them for wear or fouling.
Check the ignition coil using a multimeter for proper resistance readings.
Replace any faulty ignition components, including spark plugs or ignition coils.

5. Reassemble and Test

Reconnect the battery and all components.
Ensure all connections are secure and fuses are intact.
Attempt to start the vehicle.
