Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool if it has been recently running.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge
Check the fuel pressure at the rail to ensure it meets manufacturer specifications.
If pressure is low, inspect the fuel filter for clogs and replace it if necessary.
Test the fuel pump relay and wiring for proper operation and replace if defective.

3. Electrical System Examination

Tools Required: Multimeter
Test the battery voltage; it should read around 12.6 volts when fully charged.
Inspect battery terminals for corrosion and clean them if necessary.
Check the alternator output to ensure it is charging the battery correctly (should be between 13.5 and 14.5 volts when the engine is running).

4. Air Intake and Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth
Remove the throttle body from the intake manifold.
Clean the throttle plate and housing using throttle body cleaner and a soft cloth.
Reinstall the throttle body and ensure all gaskets are in good condition.

5. Sensor Checks

Inspect the crankshaft and camshaft position sensors for proper operation.
Use a multimeter to check for resistance and continuity in the sensor wiring.
Replace any sensors that are found to be faulty.
