Need help !!!

Crank sensor and wires were burnt replaced and did crank relearn. But still having all cylinders misfiring. Checked o2 sensors and they are working fine.Done every thing below also. having a problem with my LS-1.I have changed the coils , coil wiring harness ,fuel injectors , plugs , plug wires, and still having a misfire code pop up on cylinder 8. Also done compression and compression is fine. The car misfires on and off. If anyone has any sugestions let me know. i need help. thanks in advance .

How did the wires get burnt? Did you fix all the wires in the harness? What codes are you throwing?
