BMW 732i 1985 Bosch Motronic - Non starter Archived Message

Fellow Techs,
Have this BMW as a non-runner
Tests Carried out: CKP and Reference (Cyl 1) sensors waveform ok at ECU.
We do not have ignition or injection pulses. Have tested ECU, we had it returned as non faulty.
ECU powers up all the sensors (@ 5V) but fails to provide the necessary pulses to ign and inj.
Continuity between ECU and coil/injectors is good.
We failed to locate a wiring diagram for this vehicle, ECU has 2 35pin sockets, autodata only lists vehicles with 1, alldata is the same.
Regards and Happy New Year to all
