2009 Toyota Corolla (Won't start)

Hello,
So basically we have had this problem with our 2009 Toyota Corolla LE 1.8 L for about 4 months. It started off not wanting to start and we had to give it a little bit of gas (which we shouldn't have to do because it is fuel injected) to get it started. It will only start once in the morning and after that it will not turn on.
We are not sure what to do and the codes that have appeared are the following:
p0015, p0300, p0301, p0303 --> we reset the codes after doing some work on the started, plugs and ignition coils. Then the following podes appeared later:
p0302

Here is everything that we have done on the car so far:

Put in new spark plugs
Timing is correct
Ignition coils are all fine
Crank sensor is working
Both cam sensors are working
No fuses are blown
Vacuum is working correctly
Fuel injectors are spraying correctly
Compression is correct is all cylinders
Fuel is not clogged
Fuel pump is working and fuel line is clear
Belts are all perfect
Starter is working
Mass air flow is working
Fuel pressure check was in speck

(Everything we have done so far was checked by either the dealer or several automotive mechanics).

Some advice would be really helpful! If you have any questions please don't hesitate to ask. Thanks!
