  • 2000 Crown Vic fuel rail pressure

    Does anyone know what the fuel rail pressure should be on a factory Crown Vic CNG system ? I'm getting a check engine light and a low pressure sensor code--I can't tell if it is the sensor or actually low pressure. The light only goes on during a start condition--if I reset it, it never comes on until the next restart. The car runs perfectly. If the pressure is low, I'll probably finally install the new filter that's been sitting on my workbench for months. I plan on borrowing a fuel pressure gage tomorrow but have no idea what is expected.

    I believe the pressure is 125 to the injectors. If the car is running perfectly, I'd say the sensor is suspect. Is the code P1092?
