Intermittent issue with engine sputtering, shutting off and no start

Hi there, I have the car listed above LE. I have had intermittent problems over the past year with the vehicle sputtering, shutting off, and sometimes no-starting. 6 months ago I replaced the fuel pump relay, and experienced no symptoms for quite a while, then they came back. I then replaced the fuel filter, same result, fine for a while, then came back. Last week, the symptoms came back with a vengeance, shut off on me, and no-started for a while. I also experienced, for the first time, the smell of gas. By no-starting, I mean I would have to cycle the key on and off, and wait a bit, and eventually it would start. So I replaced the fuel pump, test drove it, and the symptoms are still there. I'm guessing my next step would be to replace the fuel pressure regulator, located right next to the fuel pump I just replaced? I really don't have a way to pressure check it, and do not want to risk driving it into town (20 miles).
