    327i build probelm

    I am lost
    My car 1985 325e
    My parts car 1991 325i

    Im guessing you can tell what I have done.... trying to get done.
    I swapped all the parts from the 1991 to my 85 block : 885 head, ecu, wiring harness, toothed crank pulley, alternator, starter, all sensors, thermostat housing.
    I have installed it all into my car and I used this link to wire up the connection between c101 and c104


    The problems:

    No fuel... unless I jump power to fuse number 11 from another with power, but I'm sure with some more time into that I can figure that out.

    No spark... I get power to my coil but that's as far as it goes, I pulled a plug and there's no spark...

    I'm just looking for some suggestion right now because I have tried as much as I can think of. I'm sure its in the wiring but I have looked and started testing and still nothing. I'm going to upload some picture in the near future just actually have to take some.

      oops

      So I thought I found the problem for no spark, my ecu is not getting power. I tested that on pin out 18 ecu. So i decided to take 12v power directly from the battery junction, well I cooked the power line that originally was supposed to give power. Where would I get power from to my ecu? No worries I didnt plug the loom into my ecu.

        wait, you cooked the line? you mean you threw a battery line into the power line (in the loom) for the ecu? you should be able to just pop a new fuse for that.

          This sounds like crank position sensor, going by memory if its not working it will halt fuel and spark delivery
