Things don't just die without any historical reasons.
You say "you have tried... : tried what?
When/How did that start?
What sort of service records?
How are the batteries charge level ?
You know you need ignition ON to power up ECU, right. (Fan spinning is an indication ECU maybe on vacations...) - Go ahead unplug the fan until you can get the engine running.
What faults are other modules reporting ??
