I don't know who else to ask besides my friendly fellow taurus/sable owners. I know this is related to the fuel rail pressure sensor, but if any of you have experience with this specific trouble code, was it solved by replacing the sensor or was it something else relating to the pressure of the fuel system... I want to be completely positive if it is the sensor or not because I don't wanna spend $150+ on a part that I didn't need...

Here's what happened, I was out at the movies last night with a friend, I parked, the car started sputtering so I shut it off. The check engine light came on and the oil light flashed so I got out and checked oil, coolant, spark plugs, etc. Everything was fine. Checked for leaks - no leaks. I go to start the car and didn't hear the fuel pressurizing. It started, but it was acting like it was gonna die out from no fuel. I put it in drive and moved up a bit and it was being sluggish as hell. Then it died out. I tried starting it back up and it wouldn't start. Same thing - I didn't hear it pressurize. I let it sit for a minute, called family to let them know whats going on then like a miracle I turned the key and I heard the fuel pressurize and it started up like a champ as if nothing at all happened. It wasn't hesitating, jolting, nothing. I only felt the small misfires I always feel.

What do you guys think?

I once had a pending P0191 code. I had just filled up with gas, and as I pulled out into traffic from the gas station, the car sputtered and would not accelerate. I drifted into a parking lot, and as soon as the car stopped, it died. I waited about two minutes and tried to restart it, and miraculously, it started. The car then ran fine all the way home. I took the car to the dealer, where they said everything tested OK, but it sounded like the problem was the fuel pump from the symptoms that I described. So I had the fuel pump replaced, and haven't had a problem since (except for the faulty pump that was put in my car, but that's another story).
