    280zx turbo timing going crazy

    in S130 Series - 280ZX

    Seems unlikely.  You didn't confirm that you saw page EFEC-67.  Why would you look through the suspension chapters?  Seems more like you're just not sure what you're looking at.  You said you can't see anything but then implied that you can see 0 and 20.  And "spinning the cam gear" doesn't have anything to do with anything really.  Certainly not erratic ignition timing.

     

    Sorry, just trying to find your level.  You're obviously new to engines so you're going to have to put some work in.  

     

    Give some background on you, and how long you've had the car.  If this is a new problem, if the engine has ever run right, did you do somehtng and this problem cropped up, stuff like that.  You're just a guy who has a problem he can't describe well at this point.  Good luck.

    first of all I built this car from ground up for the last 4 years of my life and daily drove it the last 3 months till this happened. I have gone threw everything in the book because everything is brand new from wheel bearings to headliner to carpet to suspension to engine being fully rebuilt and boosted... I can't see when I am trying to time it cause the mark jumps to far but right now in the middle of the day sense you asked for numbers and I looked I gave a guess of where it was jumping from. Also i have spun the cam gear before and had the same problem but this time around it was the first thing I checked and had no issues.

    I have been threw every page of the manual and found nothing I could use for this. Sadly the timing mark does not even hit any numbers it's so far off. If I had to guess to try and better explain I'd say it bounces from 0 to 20 to 0 to 20 to 0 to 20 to 0 to 20 non stop.

     

    As we speak I just checked the hermonic ballancer and that has no play. I put it to TDC and the rotor was pointing to #1 so I did not spin the cam gear or anything random like that =\

    I think i may have posted this twice? Sorry if I did =\

     

    Soooooo still trying to figure out why my timing mark is constantly jumping back and forth. Just put in a new crank angle sensor and had no change. I have been searching all over, reading anything and everything just to get no where.. I can't seem to find anyone that has seen this or similar to. Anyone have any advice or had this problem... love to get some help..

     

    Tried
    -cap and rotor
    -plug wires
    -plugs
    -Ignition coil

    -harmonic balancer

    -new crank angle

    -different timing gun

    -no play in dizzy or shaft
