First realize this is an AC signal, so if you are measuring with a good DC meter, it may show nothing.
On the motor one terminal is ground, the other two are out of phase square wave signals.
You may have to use an O;scope to see these, or at least a decent AC meter.
If there is truly no signal:
this signal is directly derived in the controller box (next to Lambda controller at right kick panel) from a signal from the coil. Either the black box controller is bad, or the wiring from the coil is open.
Get box from junkyard..
Also they can be repaired sometimes, I have done this and maybe could fix yours if interested email me (near Boston MA)
