When you turn the key on without cranking the engine over do you hear the fuel pump run inside the fuel tank for about 5 seconds? If not, you could have a bad fuel pump or fuel pump relay. Here is a guide to help as well and I have included how to change the fuel pump out and the location of the fuel pump relay. Also, you can try some starting fluid to see if it will run to help confirm the fuel pump issue.

Check out the images (below). Please let us know what you find. We are interested to see what it is.

I believe I hear the fuel pump not sure. But would the purge valve keep my car from not starting? I have 3 codes that come up p0172, p0175 and p0446 and I have already changed my EVAP vent solenoid valve.

None of these codes will make it not start. But they can be a clue, can you try to unplug the MAF sensor so we can see if the engine will start with the sensor? Here is the location, let me know what happens.
