I highly recommend getting a lion jump pack.

I find Boxsters are hard on batteries. Just vampire drains.

That being said. What exactly do you mean by wing turn over?

Starter turns, won’t fire?

Or no engine rotation what do ever?

If you turn the key and it won’t turn over
It’s either the battery, or sometimes the ignition switch.
The clutch pedal switch also comes into play.

If it turns over, but not fire, it’s typically immobilizer, fuel, or crank position sensor related.

I might have missed a few others, but this is a good start.
