    z24s vacuum advance

    Hi !! I have a question about vacuum advance. I have read that the vacuum is highest at idle and when you open the carburetor throttle the,(wot), vacuum decrease. I tested the vacuum advance on my distributor...at idle the vacuum works nice.,, (it engage) ,, ..but when i open the carbuteror throttle , (wot) , the vacuum stays on ...does not go back to initial.,(except when i stop the engine) .. ..ANY IDEAS ???
  3. Thank you for all the help ... specialist assistance would be appreciated !!!! Yesterday i replaced all ground cables from battery to engine .. and engine to chassis....(basically only two wires)...I also replaced the condenser and points,,new ones....lets se how long they will last...(the spark is still weak) Today i try to replace the fuel pump relay...maybe that affects the ignition somehow...(https://axleaddict.com/auto-repair/The-Datsun-and-Nissan-Pickup-Fuel-Pump-Relay-What-the-Haynes-Automotive-Repair-Manual-Wont-Tell-You)...a longshot , i know... last year we could not get a nissan almera to start ..... after 10 days of diagnostics we were ready to give up ...nothing worked. By a coincidence, I saw that one stop light was out of order , i replaced it and the stupid engine started...i disconnected the light again and the engine would not start..reconnected the light and the engine started....!!!.....mysterious nissan !!!
  4. I am convinced I have a ground issue , I have checked everything else. Ignition coil is ok ,new , (1.4-1.7ohm primary) , Coil resistor ok , (1.6ohm). Points and condenser new , (condenser 0.22 microfarad). I tested one of the sparkplugs for spark , touching the point where the ground wire goes to engine from battery....very weak spark !! However....!!!!.....esterday i happen to touch the high tension cable from the coil to dizzy....my hand touched the chassis at the same time...i felt a weak current on my hand. Immediately I thought there was something wrong with the cable so I replaced it with a new one ... but the same happen with the new one ... so i tested another new one ... the same ... i felt the current. I might try to replace the ground cable from the battery to the engine...!! Every thing else on the car works fine....(except for the fuel pump relay) , start motor ok .. lights ok ,
  5. HI !!! I do not own a pathfinder, I have a king cab, 4x4, d21 with what i believe has the same engine as some of the older pathfinders. (z24s carburated, point ignition, 4 plugs, 1 ignition coil and external resistor and single points). There is only 2 wires on the distributor , one is blue and is going to the ignition coil negative side , if disconnected the engine stops. The other on is Black with a yellow stripe on it and it goes in to the main harness., if disconnected nothing happens . The black/yellow wire is supposed to be for the distributor/ignition ground ,,, !!/?? I was convinced that the distributor had ground from the engine block and that was enough for the ignition to work properly. The problem is that i keep burning my points and condenser , they may last one week at most and my ignition timing keeps fluctuate.
  6. I do not own a pathfinder, I have a king cab, 4x4, d21 with what i believe is the same engine as you, (z24s carburated, point ignition, 4 plugs, 1 ignition coil and external resistor and single points. I saw the second photo of your distributor that it has only 2 wires connected to the it, i have the same but the white wire on my distributor is black with yellow stripe on it, the blue one is the same on mine. The white on yours is the distributor / ignition ground if I'm not mistaken, i belive it must be the same on mine ... just different collors on wire. I have a ignition ground issue on my engine, if i disconnect the blue one the engine stops, but if i disconnect the black / yellow one nothing happens. The problem is that i keep burning my points and condenser , they may last one week at most and my ignition timing keeps fluctuate. What happens if you disconnect the white wire on your distributor ?? PS: sorry for my bad english..
