I now have the following information. pin 58 on the ecu - green w red stripe. left hand terminal on coilpack connector. 1.37 ign on cranking goes up to 1.77 pin 59 on the ecu - green w yellow stripe rh term on coilpack connector. 1.39 ign on cranking goes up to 1.79 pin 57 (or 37) on the ecu - black wire 12.2v with ignition on. centre term on coilpack remains constant.
These low voltages would explain why there is no spark but I can't understand why they would be so low. The wire from the old coil loom to the ecu runs through a black box which does contain at least one relay which can be heard latching upon switching the ignition on.

On cars with a mechanical speedo the cable attaches to the speed sensor which in turn attaches to the gearbox. On cars with a electronic speedo there is no outlet for the speedo cable and the electronic speedo uses the same signal as the ecu. Without it fitted you will have idle speed issues though nothing major and it's certainly not causing your current problem. The old coil connection should have power on the black wire, the green wire just goes back to the rev counter. I hope this loom adaptor has several relays in it and it isn't trying to run the Zetec power straight from the old coil feed. The black wire on the old ignition coil should just be feeding a relay, this is turn should switch battery power to the ecu.
