HI !!!
I do not own a pathfinder, I have a king cab, 4x4, d21 with what i believe has the same engine as some of the older pathfinders.
(z24s carburated, point ignition, 4 plugs, 1 ignition coil and external resistor and single points).
There is only 2 wires on the distributor , one is blue and is going to the ignition coil negative side , if disconnected the engine stops.
The other on is Black with a yellow stripe on it and it goes in to the main harness., if disconnected nothing happens .
The black/yellow wire is supposed to be for the distributor/ignition ground ,,, !!/??
I was convinced that the distributor had ground from the engine block and that was enough for the ignition to work properly.
The problem is that i keep burning my points and condenser , they may last one week at most and my ignition timing keeps fluctuate.
