A short to power on the regulator A control wire. An open in the regulator A ground side. A regulator A solenoid with high resistance or an open coil. A corroded or water-filled regulator A connector. A PCM driver stuck high.

Check the regulator A connector for corrosion or water. Test the control circuit for a short to battery voltage. Measure regulator A coil resistance and look for an open. Check the regulator A ground circuit for continuity. Replace the fuel pressure regulator A if the coil is open. Clear the code and retest.
