CTS are very sensitive to problems with the hose between the air filter box and the intake. If it is not on good or leaks, it will cause the car to run rough, or die immediately after starting.

most of the time its the sensor that cause this,id try replacing the sensor on it,that usually fixes that code,but you have to get the code cleared off with a scanner ,and then re-scan it to make sure it doesn't come up again,good luck with it.

Hi. the fuel pressure sensor is part of the fuel pump assembly. You will have to remove the fuel pump to replace this. I would go ahead and replace the fuel pump while you are there.You will have to Pull the strainer off the fuel pump and discard it. remove the retaining clip for the fuel pressure regulator so that you can remove the fuel pressure regulator. Disconnect the electrical connections for the fuel pumps and the fuel level sensor. Remove the retaining clip for the fuel level sensor and remove the fuel level sensor by squeezing the locking tangs. the sensor is incorporated in this area.

Please rate and god bless.
