1994 Ford Escort 1994 Ford Escort starting problem

I recently got the car and have had very few problems with it aside from the low acceleration and a faulty battery cable. My car had trouble starting yesterday (The engine sputtered several times but eventually turned over). Later, after getting gas, the car started fine (No sputtering, just startd right up). This morning, however, when I got in to start my car, the engine just kept sputtering but did NOT turn over. I tried pressing down on the gas pedal several times (Worked in a Cavalier I had) and still nothing but cranking with no ignition. At this point I'm just looking for what could be the cause of the problem and how much it would cost to replace it.
