Starter turns engine over, has spark, but will not start. on 2001 Kia Rio

5 months ago, went to start car, but would not start. Engine turned over and there was spark. All related fuses were good. Any suggestions?

Spray some starting fluid down intake tube and see if briefly starts. If so you know it's fuel related- maybe filter is plugged or possibly fuel pump relay or pump.
