I'm rather stumped, and since I'm trying to get as much information as I can, I figured I'd ask here as well as other people.

I've got a 1992 Subaru Legacy Turbo that won't start. The engine acts like it wants to, but doesn't start. Sometimes it almost starts, but doesn't.

The battery is good and has a good connection. It isn't flooded either, as I let it sit overnight before trying it again. I replaced the fuel filter today just to be on the safe side, but it's not starting yet.

My grandpa and friend both thought it seemed like it wasn't gettting enough fuel.

Ideas?

And yes, not only do I come to Doomworld for physics questions, but also for car questions ;)
