Check if rev counter moves when cranking , if not could be crank sensor / wiring . Check if you can hear fuel pump buzz for a few seconds when switching ignition on . Try spraying easy start into intake and if runs then fuel problem . If so check / change fuel filter

I had/have a similar problem with my 2002 Rover 45, sometimes failing to start with the engine cranking nicely (so no battery problems fortunately).
In my case after waiting a few minutes the engine would start normally.
The only thing I found is that it happened when the tank was (almost) empty, when filled it went away. This doesn’t explain the problem but at least it solves the problem.

^ Above post . Shouldn't make any difference if fuel pump is operating as suggested . By switching it on and off a few times by trying you probably primed the fuel system which should not be required unless weak fuel pump or drawing air

Hope that's all it is , but if it fails you dont usually hear fuel pump when switching ignition on
