If the vehicle would not start due to a no ignition spark issue, the no ignition spark has to be done first, causes such as a non operational crankshaft position sensor, would be the first to inspect for.If you have a scan tool that can read data, On the scan tool RPM during cranking , the RPM has to be above 250 RPM before a ignition is initiated. If not the CKP would need to be furthered investigated
