It turns over it just won't fire. Its has a new timing chain and it is in time. It has a new ignition module, cam sensor, and crankshaft sensor. There is power going to all the wires. Everything seems to work. It just won't start. i rented a computer from autozone but it says no codes. What could possibly be wrong with it and how can i fix it?

No codes and power throughout your ignition system, inspect your fuses (ECM) and check for fuel pressure at the shredder valve. You need 62-65 PSI for start ups, anything less will cause your engine a no start. The fuel injectors need 62-65 PSI to have them work and will drop about 5PSI when the engine is running.
Try spraying some carb cleaner or very small amount of starter fluid through your throttle body. Don't poor gas through your throttle body, if the gas catches fire. It will burn up your fuel injection system adding more cost to your repair.
If you have less then 62 PSI inspect the ground wire to your fuel pump sending unit before replacing your sending unit. Good luck and keep us posted.
