M50 swap problems­čśú

So, the car cranks... but it doesn't fire up. It doesn't get gas or spark. I looked it up and i found allot of things.. the car itself is an 95 318i with an m43b18. The new engine is an m50b20 vanos from 93. I readed allot of forums about EWS problems, they had the same problem like me. Cranks but no spark or gas. I tried to bypas the yellow conector, but the car did nothing even diden't crank. I also tried to wire the fuel pump. I heard it buzzing so it still works, first i thought it broke... so I don't know what to do from now???
