need your opinion please!

Hi everyone, I'm new here, I need some opinions on why my car isn't starting, It turns over but dosent start. I'm getting a spark, the fuel pump is working, just replaced the fuel filter, checked the plugs, the battery is fine, its getting air, the compression is good too....soooo what the hell??????? am i missing something,???? I just did some work on it, new rad, new water pump, thermostat, and I took it for a spin a few days ago after I finished doing the work and it ran fine, but for the past few days I just can't get it going at all. like I say it turns over and it seems like it should work...??? when I pulled the plugs today after I tried to start it they were wet with gas, thats ok right??..
anyways what am i missing???? -Robby
