Nissan Repair: NO SPARK, continuity test, nissan maxima

Question
96 NISSAN MAXIMA THERE IS INJECTOR PULSE!!!! THE PROBLEM ITS DOESNT HAVE SPARK IN THREE COILS. THERE IS POWER IN ALL OF THEM. THERE IS GROUND IN ALL OF THEM. THE THRID WIRE IS HARD TO DETERMINE IF IS POWER OR A GROUND? BUT WE DO GET A READING OF .41MV AT KEY ON AND AROUND .246MV AT CRANKING AND IT DOES FLUCTUATE ON (THIS IS ON THE ONES THAT DONT SPARK)  ON THE ONES THAT HAVE SPARK IT LOOKS LIKE IT CUTS THE POWER FOR A SPILTSECOND I DID A CONTINUITY TEST ON THE WIRES AND IM TESTING THE OUTPUT FROM THE COMPUTER. I SWITCHED THE COILS SO I DONT THINK ITS THE COILS. THE REAL THRILLER IS IT SOMETIMES STARTS BUT VERY HARD CRANKING A LOT HOLDING THE ACCELERATOR. TRIED NEW CRANK AND A DIFFERENT GOOD CAM SENSOR

Answer
upon research on this car, theres a right and left coil.  i would highly reccomend going to a salvage yard and try replacing some ignition parts from a used vehcile to check with your car to see if this corrects your situation.  if it doesnt work, just return the part to the garage and tell them "your welcome" for taking out a part for them.  just let them know you will pay them if it works.  most places are pretty easy about this.  honestly, if all bolt ons dont fix this problem, then dont kill my score by rating me a 4, i honestly dont know exactly your cure, im just giving you some ideas!!! let me know how this turns out.  xxp_sebby@yahoo.com
