Welcome to the Forum!
The DME provides the ground for the coils, and does the break as if it was the points. So I would first test the CPS first, for I have seen cheap ones fail right out of the box.

Or...the EWS is unhappy. Do you have a scan tool which can read all the computers on a BMW?

You need scan tools. A windows laptop with a k-dcan cable, 20-pin adapter, and INPA software can be a good basic scanner to read codes in the modules you need.
Bypassing is not a fix for anything.
Do you have rpm signal on the instrument cluster when you are cranking? If no, then you don't have crank position/engine rpm reading. No amount of bypassing will solve that.

Theres No signal, its the third cps i try.. im suspecting som bad wires as the wiring isnt the best anymore. Also No fuel to the rail, is it something with the cps signal allowing fuel flow?

You need to talk to the computers, and find out what they know.

So when exactly did your car stop sending spark?
In your first message it suggests it was at random.
