N52B30 crank no start

Please delete if not allowed

Hello, I have an E82 125i N52B30

Crank no start since November after RCG and ESS.

Car back in my possession, relearnt vavletronic limits, checked all grounds, have spark and fuel.

Took a fully charged battery and jump pack today and took a video. Cannot post here

Codes are all over the place. I assume the dead battery has a lot to do with most.

2DEC, 2DED, 5DF4, 5DB6, 93D0, A559, 931D, 9319,931A, A0B5, 9D11, 9CB5, A738, A669

Starter worn out from all the cranking?
Cylinders flooded with fuel?

Any help is appreciated

Try to check everything you disconnected, also in the jump terminals area in the engine bay

If you have inpa you can check the eccentric shaft sensor angle with it to exclude a bad new sensor
Does the car have power to everything else?
Are those the codes you get after erasing em and then starting to crank?

I have checked so many times and I’ve had my brother check also just to be sure.
I have power to the lights and radio.
No access to inpa, been trying to get someone with it to come have a look.
