    M50b20TU no sparks, fuelpump doesnt work

    Well greetings e30lovers.

    The problem is following: I have done the swap, all the engine parts installed correctly. Now harness and wiring - here is the problem. Motor cranks, but no spark, and fuelpump doesnt response anyhow. Tried to fire it up with starting fluid, but no reaction, Tried different wiring specs for my e30 88` 320i, but problem is still nod defined. I am thinking of: Ecu doesnt have voltage, CPS is dead, or EWS... The last one : i simply dont have it.
    Would you kindly give me an advice, where I am wrong? I will send the pictures of the harness in future.
