Engine Cold start cranking not starting

[Hussain_bo_Hamad]

Hi,
I have the following setup:

BMW M50b25 engine dbw k20 coils oem 200cc injectors hall primary trigger oem cam trigger v3.060 software same firmware.

Engine management is ECUMASTER EMU Black.

The issue,

Engine start in cranking then dies.

During output test timing lights is flashing just fine, but during engine cranking it’s not flashing means ecu is not sending signal to ignition coils, spark plugs will be fuel flooded.

During cranking I change the coils settings sequential waste spark invert phase but it’s same.

Why does this happen, and what am I missing here?

Cam sensor is vr on nonvanos and hall on vanos engines, which is yours?

Does it run in wasted spark?

I changed it to hall sensor did the air gap as requested, yes on waste spark crank then shuts off.
