Solution

1. Preparation

Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Test the Fuel System

Tools Required: Fuel pressure gauge
Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Attach the fuel pressure gauge to the fuel rail test port.
Start the engine and check the fuel pressure reading; it should be within the manufacturer's specifications (generally around 40-50 psi for most vehicles).
If the pressure is low, inspect the fuel pump and fuel filter for blockages or failure.

3. Examine the Ignition System

Tools Required: Multimeter, spark plug socket
Reconnect the battery and use the multimeter to check the battery voltage; it should be around 12.6 volts.
Remove one spark plug from the engine and inspect for wear or damage.
Check for spark by connecting the spark plug wire and grounding it against the engine while cranking the engine. If there's no spark, replace the faulty ignition coil or spark plug.

4. Transmission Inspection

Tools Required: Torque wrench, socket set
Check the transmission fluid level using the dipstick; if low, refill with the manufacturer-recommended fluid type.
Inspect for any transmission fluid leaks and look for signs of burnt fluid.
If necessary, remove the transmission pan to inspect the filter and replace it if clogged.

5. Final Assembly and Testing

Reassemble any components that were removed during inspection, ensuring everything is torqued to the manufacturer's specifications.
Reconnect the battery.
Start the engine and monitor for any abnormal sounds or warning lights.
