The car service recently done then I drove, the next morning it is only cranking but does not want to start again. My question is, can fuel and sparks related to a crank position sensor or can this be a failure of an ECU? Fuel pump tested and is working perfect, all ignition coils also get tested and they are good, plus I checked fuses and relays. The engine fan is going on once ignition turned on.

Have you had it scanned for any trouble codes pending, current or permanent? That would be the first step.

If you already checked for proper spark then verify that you have fuel pressure. If pressure is good then check the fuel injectors for a pulse.

Here is a repair guide for a crank no start:
