Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery and Charging System Check

Sub-steps:
1. Use the multimeter to check the battery voltage, which should be around 12.6 volts when fully charged.
2. Start the engine and recheck the voltage; it should rise to about 13.7 to 14.7 volts.
3. Inspect battery terminals for corrosion and clean if necessary.
4. If the battery or alternator is faulty, replace as needed.

3. Fuel System Inspection

Sub-steps:
1. Locate the fuel pump fuse and relay, checking for continuity and proper function.
2. Attach a fuel pressure gauge to the fuel rail and turn the ignition on (don’t start) to check pressure; it should be within manufacturer specifications.
3. If pressure is low, inspect the fuel filter for clogs and replace if necessary.
4. Consider replacing the fuel pump if it is failing.

4. Ignition System Repair

Sub-steps:
1. Remove the spark plug wires and inspect for wear or damage.
2. Check each spark plug for fouling or excessive wear; replace if necessary.
3. Test ignition coils with a multimeter for resistance; replace any faulty coils.
4. Reassemble all components ensuring proper torque specifications.

5. Air Intake System Check

Sub-steps:
1. Inspect the air filter for dirt and replace if clogged.
2. Check for any vacuum leaks in hoses or connections leading to the intake manifold.
3. Clean the throttle body if carbon buildup is present.
