QUESTION: sorry 2006 grand prix GXP 5.3 V-8

Answer
The sending unit that the fuel pump is in is where the tank pressure sensor is. On that year car the gas tank has to be removed from the car in order to get the sensor out. pree 2004 there was an access door in the trunk yours doesn't have that so the tank has to be removed.
