(Thread Starter) |   Not Ranked : 0 score  Bad Fuel Pressure Sensor? Say i start the car. Everything is running dandy. I stop the engine by turning the key. turn key back on but dont start car yet (Everything has power, dashhawk is still running etc) My Fuel DI pressure will steadily rise from ~400 psi too like 1600 psi even though the engine is off. Has anyone else noticed this behavior? Next time you drive you could check and see on your DH or Cobb AP? If i turn the key when the car has been sitting the pressure sticks at 60 psi like it should. -Phil

| Not Ranked : 0 score Funny enough I was sitting in a parking lot tonight after running into the store. I turn the key on but didn't start the car but the ap showed 1200 psi pressure and was slowly climbing. I thought it was weird but car runs fine though. |
