2000 Plymouth Voyager. 3.0 Distributor ignition. NO SPARK!!!!

In trying to solve problem, I've replaced the coil, cap & rotor. I am baffled as to why I'm not getting any spark.

I pulled the plug going to the coil. I followed the testing procedures outlined in the forum for testing the ASD relay & crankshaft position sensor. I get a brief flash of power to the coil when the key is turned to the "on" position. Then when I crank it over, I get continuous power to the coil. So, it appears I'm getting power to the coil, but no spark from it. Also, I've replaced the coil to fix it to no avail. If it were the crankshaft position sensor, I'd think I wouldn't get power to the coil.

What should I look at next, and how do I test just the crankshaft position sensor?

HELP!!!!!!!!!!!!!!!

I don't know the specifics of the caravan, but in general, a coil doesn't get constant power, it gets pulses of power. The coil windings saturate when it is getting power, then when the power is removed from the coil, the collapse of the magnetic field is what induces the large secondary voltage. If you are getting constant power and ground to the coil, something is wrong. Either the ground, or the positive voltage should be in pulses when the engine is cranking.
