Posted August 11, 200420 yr comment_90691 I have recently -adjusted the carbs,-replaced the spark plugs/wires, -replaced the points with electronic ignition,-replaced any worn or bad fuel or vacuum hoses....I still get backfires and it sounds like it's missing again.So I thought maybe the firing order was backwards...Correct me if I am wrong, but clockwise it should be: 3-5-1-4-2-6, right?Please help me figure out what's wrong.Thanks.

August 11, 200420 yr comment_90693 1-5-3-6-2-4 In the direction tha the rotor turns. (I think that is COUNTERCLOCKWISE) Try that. I think you got it out of sequence.

August 11, 200420 yr Author comment_90695 I counted that clockwise.I assume the rotor runs clockwise also, no? Link to comment https://www.classiczcars.com/forums/topic/12822-240z-runnin-funny/#findComment-90695 Share on other sites More sharing options...
August 11, 200420 yr comment_90696 I don't think so. Anyway, wire it like this attached photo and you'll be correctly wired. Link to comment https://www.classiczcars.com/forums/topic/12822-240z-runnin-funny/#findComment-90696 Share on other sites More sharing options...

August 11, 200420 yr comment_90699 Here...check out this link/photo.This is what mine looks like.Does that look like the correct setup?http://www.classiczcars.com/photopost/showphoto.php?photo=8934&sort=1&cat=all&page=1That is my photo. Rotor moves COUNTERCLOCKWISE. "IF" you have it like the photo shows, you are wired correctly on that end of the plug wires. Double check the other end of the wires, it's easy to get 2,3 or 3,4 or 4,5 mixed up.(damn internet connection crashed) Link to comment https://www.classiczcars.com/forums/topic/12822-240z-runnin-funny/#findComment-90699 Share on other sites More sharing options...

August 11, 200420 yr comment_90702 I editted my last post since you posted. Double check both ends of the wires.If the engine WAS NOT running this way before you worked on it, it's likely that something isn't adjusted right, and doubtful that you would need a new engine. What kind of electronic ignition did you install? Did you adjust the timing after installing the new ignition?

August 11, 200420 yr comment_90703 Adjusted the tappets before you tuned the car? Could also be a fuel issue, do you have an itermittant blockage? Link to comment https://www.classiczcars.com/forums/topic/12822-240z-runnin-funny/#findComment-90703 Share on other sites More sharing options...
