Quest cranks but will not start
 

I have a 2004 Nissan Quest. Basically, one day I'm driving along and power totally cuts off. I mean engine is not running at all.

I checked the common thing that happens on these, which is a rusted ECM but mine is not rusted. Issue is, I am not getting spark at all on any of the coils.

I replaced the camshaft and crankshaft position sensors, but nothing. I will just crank and crank but never turn over. I am not showing any codes.

Anyone may have a solution, or something to check out? Thanks!
