A zero reading in ohms means the connections are not mating up correctly = the Provari can't tell there's a tank connected. No electrical current to fire the coils in the tanks means no vapor produced. Look here for some possible solutions:

Contact Provape via email ticket if you don't find your answer.
Also, remove the tank and look at the connector pin on the Provari. Is there any e-liquid there? If so, take a paper towel and wipe it clean. Juice on the connector pin will cause no conductivity to the juice attachment.
Did you try the cartomizers and Protank on your Ego? Same results? Chances are great there is user error involved here.
Proper priming the cartomizer is of extreme importance, not enough juice will cause burning of the polyfiller resulting in a burnt taste. Some people can't stand Low Resistance cartomizers or dual coil cartomizers, switching to
standard resistance cartomizers and
single coil cartomizers can make all the difference in the world.
Filling, or Priming, the Cartomizer - "Drip & Flip" Method:
This is the method that I have used successfully. To keep juice out of the center air hole when filling the carto I plug it with half of a wood tooth pick.
The most important step is to completely fill the carto with enough juice. How well you do this step will determine how well this carto will perform for the rest of its life in the tank. Take your time & do it right.
I hold the carto at a slight angle, and rotate it around as I drip liquid onto the polyfill. When the fibers look like a slushy drink, I shake the carto down like a thermometer. This produces the same effect as a centrifuge, forcing the juice down into the carto bottom.
I then add more drops, and shake it down again. Repeat this process until the polyfill will absorb no more liquid. The fibers should glisten, wet but not pooling. Now the carto is ready to vape.
