Need Help! Motor turns....won't start

So I know you guys probably get tired of seeing this thread get started.....over and over again, but here we go.

I have a 73 swinger..225 single barrel holley, electronic ignition. I don't exactly drive it daily, but I do use the car to get back and forth to work on occasion. (4 mi round trip). I went to leave work last night and the car just won't turn over. Got a ride this morning and tried some starting fluid to no avail..trying to track down a fuel filter right now to check that out..

what should I do...I really need to get my baby back in the driveway. any help would be greatly appreciated.
