I have a 2006 Kia Spectra EX that will turnover, but will not start. I have already replaced the ignition coil, spark plugs & wires, and the fuel pump. What are some of the other things that I need to troubleshoot in order to find the main cause of my car not starting?

Wow, you spent a lot of money for nothing.

You need to check compression. It must be about 100 lbs.
You need to check for fuel pressure with a gauge.
You need to check for spark.

If any of these are at fault, then you need to find out why. You should have a shop at least diag it for you and then you could do the work yourself. This way you are not wasting money on useless parts.

The list of things that you have listed were all checked, and all were good, but yet my car still turnsover, but will not start. I'm getting good sparks from my spark plugs, and I have the correct pressure rating for both the compression and fuel pressure. I can hear the two second humming sound, due to the fuel pump engaging, when i'm trying to start. The fuel pump is operating correctly. Does the computer needs to reset itself in any kind of way, or is there anything else that I need to check that will cause my car to turnover but unable to start? Thanks for taking the time to help out, but i'm pretty puzzled at this point.

No, no reseting. If you have everything, it should go. Try spraying carb cleaner into the intake and see if it fires. If it does, the computer may not be grounding the injectors.

That may be a separate issue. If you have the correct compression as you said, then the timing belt is good. Did you check the marks to verify?
