Nissan armada #4 coil no current
 

#4 coil doesn't have any current, in Nissan armada, I have tested the coil and the coil is ok, but no current to the coil. I have checked the fuse all is ohk, someone says I should check the igniter, I don't know if that can cause it, what is the location of the igniter and what do you think can cause it
