I have replaced the spark plugs, coil, and injector. I have done a compression test. They were good.

Good morning.

What was the compression?

Did you check for any vacuum leaks?

Do you have a noid light to be sure the PCM is commanding the injector to work?

Okay, so it flashed when you cranked the engine. Correct?

Beyond that, you need to pull the valve cover and inspect for valve train damage.
