Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set, wrench set.
Check battery voltage with a multimeter; it should be above 12.4 volts.
If the battery is weak or old, replace it with a new, fully charged battery.
Ensure battery terminals are clean and tight.

3. Fuel System Repair

Tools Required: Fuel pressure gauge, socket set, safety goggles.
Connect the fuel pressure gauge to the fuel rail and turn the ignition on without starting the engine.
Check the pressure; it should be within the manufacturer's specifications (typically around 40-50 PSI).
If pressure is low, inspect and replace the fuel pump if necessary.
Clean or replace fuel filters if clogged.

4. Ignition System Inspection

Tools Required: Socket set, torque wrench, spark plug socket.
Remove spark plugs and inspect for wear or fouling.
Replace spark plugs if they are worn or damaged.
Test ignition coils with a multimeter for proper resistance; replace if outside specification.

5. Sensor Inspection

Tools Required: OBD-II scanner, multimeter.
Check the MAF and TPS for proper operation using the OBD-II scanner.
Clean or replace the MAF sensor if it is dirty or malfunctioning.
Inspect wiring and connections to ensure they are secure and undamaged.
