When testing Cam and Crank sensors signal with digital metertest guidelines say five v. ac the meter displays 2 numbers every second never settling on a number
The crank sensor generates the signal for the ecm. Every revolution of the crankcase sends a momentary impulse to the ecm. That data then gives the ecm the info with which to properly coordinate the firing of the spark plugs and other critical components.
When testing the sensor most important thing to do is make sure that the sensor is receiving the 12 volts of power on one hot line and then if confirmed you check out the remaining power line for the impulse as the crank rotates. If you detect the impulse then you know the sensor is working.
Testimonial: "THANK YOU FOR YOUR INFORMATIVE RESPONSE After learning about the flow of things, I did replace the crank sensor and I now have power to all sensors and a signal and power at the top of coil. still no spark for engine to run on. South"
Based on your data it appears that the coil may be fubar and needs to be changed. Using an ohm meter check the coil for continuity. You might also check the reading you get against that of a known good coil. If coil windings are shorting to each other you will get a continuity reading but with all of the windings shorted out it will not have enough windings to generate the needed spark. That is why I am suggesting you also double check the reading you get to make sure it it about right.

It show your power and amps you genrets
Testimonial: "Thank you for your time and info I am however still trying to get spark from the coil."
