Do you have the four cylinder or 6?
I ran into a bizzare situation similar to yours with a 2.6 where everything tested out fine but....... the #1 cylinder was firing on the exhaust stroke instead of the compression stroke, exactly one revolution off. The adaptor the rotor is screwed to was split at the back side and it slipped then caught the next time the groove came around so lining everything up looked fine on the crank marks......... We actuallly found it by accident.........finally. Pull #1 plug, rotate the engine by hand and bring the piston to TDC on the compression stroke.....then check to see if the rotor is pointed to #1 wire.
The spark should jump at least a 1/2 inch of air gap and "snap" pretty noticibly. It won't necessarily be blue because of the multiple discharge system used.
