Did you check primary voltage to the coil? If okay it sounds like the crankshaft angle sensor is out.

Dis ignition. Any applicable trouble codes? In the diagram below, the top pink wire is primary voltage for the coils, probably goes hot/voltage when you turn on the key, If nothing there, check the fuse and wiring circuit.

I just had one of these in the shop so that why I say crankshaft angle sensor.

Also, engine cranking, do you have an injector pulse?

Please get back to me.
