Did you jumpstart with both jumper cables from other car direct to your battery? If so, you may have caused a spike voltage to the ecu. Best practice as per owners manual is to have positive on battery positive and negative from booster battery or car on your engine. Chances are that you have possibly popped the ecu.

Try removing the positive terminal from battery, leave it off for about 30 seconds and reconnect and try again.

It could also be your cars immobiliser causing this.

no spark can be anumber of things but basically start with a diagnostic scan and see if the management sees rpm.
