li'l report

*the Crankshaft Position sensor indicated a garbled signal when the DVOM was set @ AC voltage scale (and the tach operates,so this exhausts what I can do there).
*I get the same garbled signal from the camshaft sensor.It's new.It's impedance is okay.
*I have continuity and zero-Ohms between the igniter-to-negative terminal of the ignition coil.
*I have ditto with the ECM IGT-to-igniter circuit.
*I have ditto with the ECM IGF1-to igniter circuit.
*The ignition coil fires if bench tested.
*There is no IGT signal to the igniter.
*There won't be a ground interruption to the negative terminal of the coil without it.
*There won't be an IGF1 signal back to the ECM without it.
*All the grounds are good.

My suspicion right now is that the ECM is not 'repaired'.
After EcoModder I'm gonna dive into the official Toyota electronics tech training course which I have on a thumbdrive,courtesy of my brother.
