Well with my old PTU it wouldnt start at all put in one i got off Z1 Motorsports got a used one off them they garunteed to work so i went with that not a new one (maybe shuda went new haha) i been trying to do that continuity test on my old one and new one (series 2) cant seem to get that to work not very good with a multimeter but i did read online that when key in "ON" position you can check volts on side of ptu that goes to coils all had a reading besides one PIN the #4 would that mean no spark going to that coil? and if it is just that one could it be the wire coming from ECU might be bad connection? didnt pull any of the coils out yet tho i was kind of worried i was gonna kill my motor so i turned it off right away and posted video. So does it just sound like im not running on all cylinders? not some kinda knocking or ticking? timing? Maybe my SUB harrness is loose too ill try to wiggle that around next time i start it up it is pretty worn out
