Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and basic hand tools.
Disconnect the battery to avoid electrical issues while working on the vehicle.
Allow the engine to cool before starting repairs.

2. Fuel System Inspection

Check Fuel Pump:
- Remove the fuel pump relay from the fuse box.
- Connect the terminals to bypass the relay and listen for the pump operation.
- If silent, replace the fuel pump.
Inspect Fuel Filter:
- Locate the fuel filter (usually near the fuel tank).
- Disconnect the fuel lines using a line wrench to prevent damage.
- Replace the fuel filter if clogged or if it has not been replaced in the last 30,000 miles.

3. Ignition System Check

Inspect Spark Plugs:
- Remove the spark plug wires and unscrew the spark plugs.
- Check for wear or fouling and replace if necessary.
- Torque new plugs to manufacturer specifications (usually around 13 lb-ft).
Check Ignition Coils:
- Remove the ignition coils and test with a multimeter for proper resistance (consult service manual for specifications).
- Replace any faulty ignition coils.

4. Throttle Position Sensor (TPS) Replacement

Locate the TPS on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Install a new TPS and reconnect the electrical connector.
Adjust the TPS if the vehicle requires calibration according to the specifications.

5. Battery and Charging System Test

Use a multimeter to check battery voltage (should be 12.6 volts or more).
Start the engine and check the voltage again (should be between 13.7 to 14.7 volts).
Replace the battery if faulty or not holding charge.
