Default Crank no start

Hey guys, I’m having an issue that I can’t seem to fix. 2 weeks ago, I was able to start my swap. I couldn’t start with the key due to theft deterrent but with the key in the run position, I could jump the starter and the car would start. I’ve since then bypassed the starter relay and can now crank with the key, but now I have no spark to the plugs. Ive checked the scanner with HP Tuners and I have no engine RPM’s. I’ve swapped the crank and cam sensors. Ive check continuity over those wires but still nothing. What could it be?

Check the fuses for the harness powering the PCM circuits. Check the grounds also

Make sure you have constant power to the pcm while cranking.

Check to see the fuel pump is getting juice and activating. Next check the fuel pump relay. Make sure you're getting fuel pressure then go to spark plugs and coils.
