Tinker a three wire cable by yourself as I linked earlier, as this creates a solid and permanent connection between the contacts instead of errorprone switched contacts.
Your Ohm readings on both speed and reference sensors are not correct, the numbers you want to read is approx. 0.6 - 1.6 kOhms each. Not 970kOhms!! If the sensors really got these numbers, ther're crapped and have to be replaced! Place the test probes at the plug of each sensor directly! Otherwise you probably measure everything else but the sensors.
Visual inspection on ignition parts is senseless without electrical check. You want to read 4-6kOhms on each wire from plug to rotor cap. The rotor itself for the 3.2 Carrera has 1kOhms resistance. Wiggle the cables too while measuring to rule out broken cables.

I have 3 different DME relay's, one original, one replacement, and one solid state version. Can't see 3 of these failing at the same time. Pretty poor odds of that one.
I also doubt highly that all my plug wires have failed at once.
Thanks for the help though.
