turn the key & it shuts off.? My 2000 Grand Prix has 140k miles, when i turn the key the car shuts off immediately (sometimes). Sometimes it will be perfectly fine. I noticed a slight difference in sound under the hood. It kinda sounds like an "in and out" sound, like it gets a little loud and softer sounding. Its not noticeable, but because i have had this car for 6 years, I know it like the back of my hand. I brought it to the dealer and they said it was the PCM, (which is now replaced, $600) and I am still having the same problem. Any possible answers?
