I have a bmw 318 n46 which will not start and has no fault codes, there Is no crankshaft speed on live data and the rev counter dose not move when cranking but will run on easy start, but have no injector pulse, I have tried a new crankshaft sensor and checked all the fuses even if I unplug the crankshaft sensor and crank the engine still no fault codes, possible dme failure?

Check and see if the Dme has been water damaged

I just bought a ecu kit and fitted it but the starter motor just clicks once and puts the fault code terminal 50 output in the cas module but if I plug in my old cas module the car cranks fine and I get a rpm signal but obviously won’t start as they are not coded together, am I missing something here or is the cas module no good in ecu kit I bought
