okay so i found out my ecu was bad from be being a dumb*** not going to get into that. okay but i got my new ecu now and i got the car started. but it only runs on 2 cylinders. better than none like before the new ecu. i can start the car and itll idle on its own with 2 cylinders but it runs like poo. when its idleing i can unplug #2#4#5#6 from front to back and nothing happens runs exactly the same. checked voltage on the coil harnes and its barely getting .1-.2v on the signal wire on all those cylinders. so im thinking my ignitor is crap. just wanted to get a little advice before i go dumping more money into crap i might not need. i was thinking about the j30 ignitor but i dont know which years would work. all the ones i see at the junkyard dont have hitachi or mitsu on them anywhere. last one i wired up before my new ecu melted itself and it didnt have any marking on it but nissan and the part number. thanks for any responders.

change your ignitor if it persists , check grounds. if problem is still there after that ... you might need new coil packs
