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.

2005 Suzuki Aerio hard to start, runs fine!?

I must assume the starter cranks at full speed. if yes.
1: never tuned up.
2: flooding (use wide open throttle to clear floods) "bad spark"
3: starving for fuel
there are simple tests for all 3 failure modes.
do you wish to test , or guess.?

Starves for fuel on acceleration and wont idle right

Gas problem, likely. Have your fuel pressure tested. Fuel pump or filter may be the problem.
