How do I test the distributor coil and igniter?
I have all the tools in the world, oscilliscopes, power sources, multimeters etc.. i just need to know how to test the distributor's parts? My car for the first time in 4 years left me stranded, it was because of the distributor(160k+ miles). This is the reason I want to know how to test it.

Coil:
Primary & secondary resistance measured with simple ohm-meter. I don't remember the values. The other way for a coil to fail is insulation breakdown. So check each side with a meggar or something like that. You're looking for insulation breakdown to the case, especially from the secondary.
Ignitor:
It's an isolation amplifier of some kind. Feed it a pulsed signal, it shoud give a corresponding pulsed signal to the coil. So I guess a square-wave generator & oscilloscope??
CYP, CKP, TDC sensors:
Those are hall-effect sensors. Probably use an oscilloscope to watch while you spin the distributor shaft. I think those signals should not have continuity to ground, but they're not high voltage so an ohmmeter would be OK.
