Hi, my bmw e 38 cranks but does not make spark to start, any advice please?, I already check the EWS module and did the bypass and nothing works.

Morning Oscar

Welcome to the Forum

First any other work been done recently ? If so back track to see if everything was put back correctly.

There are a multitude of things that could cause what you are describing. Crank position sensor,Cam position sensors, Fuel pressure OK,, Fuses and Relays Make sure that all fuses in the under bonnet fuse relay unit are good there are a number of 30amp fuses in there (cant remember if it's 4 or 5) don't just check them visually test them for continuity or change them for a good one. Last but not least Engine earth straps (2 I believe) 

If that doesn't help then a diagnostic session is needed

Hope this helps
