it sounds likely that you do have a fuel problem. BUT, unless u have a fuel pressure tester, you probably won't know for sure if it's your fuel filter that's clogged, or if it's your fuel pump.

i know that disconnecting your fuel line and looking for fuel is an easy way to seeing if the fuel pump works, but with much more advanced computer controlled cars now, a drop in fuel pressure by about 10psi (ie. from a factory spec 50psi to 40 psi) is enough to keep a car from starting and/or running. you'll still get a shot of fuel out of the hose, but it's still not enough. then there's fuel volume... which is easy enough to check...

i would say that... if you haven't replaced your fuel filter in a while, that it's a good place to start. you can also try running some fuel injector flush through your tank in case u got some carbon built up somewhere.
