My Saturn's battery light has been on for some time now. At first we were told it was the voltage regulator but then today my hubby was on his way to the store, the car completely cut off on him. We were assuming it was either the voltage regulator or the alternator but when he plugged it into the computer to get the code, it came up with P0452. *In conclusion* he does know that the fuel (tank) pressure regulator is bad and would like to know how to install a new one. Please help!

A P0452 doesn't mean that you have a bad fuel tank pressure sensor for sure. What test's did your husband do to figure out it was a bad sensor besides read a code the computer had. That code isn't going to cause the car to die.I would fix the battery light on and the car dieing first then clear that code and see if the code come's back.I would charge the battery and start the car and see what the voltage is at the battery at idle with a multimeter. Let me know what you find.
