You can guess all day, best to do a fuel pressure test then you will know. Its simple and cheap to do, you can rent the guage at auto zone, and they also can tell you what the pressure should be.

SOURCE: i have an 1997 deville
I have a 1997 Cadillac Deville Limo that is based on the 4.6L Northstar Engine.
I think that you're on the right track changing what you thought might be the problem.
I haven't personally expeienced any problems with fuel delivery on my vehicle, but just had it tuned up with new spark plugs, wires, and air filter at 115,000 mi. or so.
I think, though, that if the fuel filter isn't clogged, and it is changed, that it will do little to make the car start better.
I agree, a fuel pump will require dropping the tank, which you probably don't want to do right away.
Good luck on this repair.

Always use a high pressure-type fuel filter assembly. Do not use a synthetic resinous fuel filter
