- Check the fuel filter: Inspect and replace the fuel filter if necessary.
- Inspect the fuel pressure regulator: Check the regulator for any signs of damage or malfunction.
- Scan the fuel pressure sensor: Use a scan tool to monitor the fuel pressure sensor's readings and verify its functionality.
- Inspect the wiring: Check the wiring connecting the fuel pressure regulator and sensor for any signs of damage or corrosion.
