Fuel reaching the injectors and spark at the plugs are good signs, but that still does not prove the engine has everything it needs to start. I would check three things next: injector pulse, fuel pressure, and compression/timing.
First, make sure the injectors are actually being commanded to fire with a noid light or scan tool. Fuel at the rail/injectors does not mean fuel is entering the cylinders. Then check actual fuel pressure, because weak pressure can still give a no-start. After that, do a compression test and verify cam/crank timing, especially if it cranks faster than normal or sounds uneven.
If there is spark but no injector pulse, I would look at ECU inputs such as the cam/crank signal, immobilizer status, and wiring. A failing camshaft position sensor can sometimes cause a crank/no-start even when other basics seem present.
In short: confirm injector pulse, correct fuel pressure, compression, and timing before replacing parts.

Did you check for a blown injector fuse? Fuel to injectors doesn't mean injectors are firing.
