If theres power at the coilpacks, use an led test light to see if they are pulsing when cranking,
If no
Use led test light to see if there is a pulse before the ignitor.
This test will tell u if the ecu is outputting a signal to the ignitor and if the ignitor is recieving and outputting a signal to the coils.
If pulse before ignitor but none out need new ignitor.
No pulse before ignitor ecu, cas or wiring issue
Is the tacho moving when u crank?
