2003 Cavalier dead. Won't start!

I have a 2003 Cavalier 4 cylinder automatic with almost 60,000 miles. I've never before had a problem with it starting or any engine problems. This morning I took my daughter to school and came home, no problem with it starting or running, nothing seemed wrong. Then in the late afternoon I went to start it and it wouldn't start. It sounds like it usually does when it first starts but it never turns over, it just makes the sound like when it's cranking but the engine doesn't fire. The dash lights and fuel gauge turn on but the engine doesn't start. All the dash lights turn off like normal except for the check engine light, the battery light, and the oil light. However, I had a friend check the battery and the oil and he says they're fine and that it sounds to him like the engine isn't getting any gas. My first thought is the fuel pump but I'm not a mechanic, far from it. It just seems weird to me that I just drove it this morning and everything was fine and then all of a sudden it won't start with no symptoms of problems before. Does a fuel pump go out that quickly with no sign of problems?
