Lead II phosphate when dissolved in water, will it conduct electricity?

On the surface, I would say yes, because it is ionic. BUT, Lead II phosphate is very insoluble based on the solubility rules. Logic makes me believe, that if it does not dissolve, there won't be any ions conducting electricity,

I am not sure what takes precedence, when it comes to an aqueous solution. thanks.

How was the question asked?

If it asks what will happen when the substance is dissolved in water, then yeah, it will conduct at least some electricity.

Really, this comes down to the definition of an electrolyte; strong electrolytes dissociate completely into ions when dissolved in water, and those solutions strongly conduct. Weak electrolytes dissociate only partially into ions in water, and conduct a little. Nonelectrolytes dissolve in water but do not form ions, and therefore do not conduct. A completely insoluble substance doesn't really fit into any of those categories. Honestly, if it dissolves at all, I would say it would conduct a little bit of electricity since all of what does dissolve will dissociate into ions.
