  • Engine dying any ideas?

    Writing this for my friend that I've been trying to help with his 1983 280zx non turbo manual . The car has started to die abruptly usually when pulling up to a stop sign. On startup it will idle fine and has not died even running/idling in neutral for up to 20mins. Things ew have done so far include

    new fuel pump
    new fuel filter
    new fuel pressure regulator
    new oil pressure sensor
    new fuel
    new coil
    new plugs, wires, rotor.

    My gut is electrical at this point but??? Could there be a relay suspect or any other electrical gremlin anyone has had that sounds like this?? Any ideas appreciated

    Thanks
    Neil

    does it start back up right away after shutting off? does the rest of the car maintain power when this happens?

      Most times yes the car restarts, at times a short est is needed. And yes the accessories continue to work.

        just wondering if anyone else might have any suggestions on where to look for a solution. He's taken it to 2 local shops so far and the issue has gone undetected. Any good shops in the Orillia/Barrie area to recommend?

          Have you diddled the idle air port? Also known as idle speed adjuster.

            No didn't consider that...as the car will idle forever as long as its standing still. We've let it it idle up to 30 minutes and its never failed. Last time he tried to drive it, it was idling for 10mins he put it in gear and it died a the end of the driveway??? It can happen that fast or at anytime at random. But usually it will happen when stopping at a red light/ stop sign. Where will i find the idle speed adjuster and when I locate it what would be my next steps??? Thanks for your reply

              For sudden stalling...take a look at the ign module that is on the side of the dizzy. A small black box. 2x2 inches approx.

                Could also maybe be restriction in gas tank, filter. but this sounds more idle related.

                  Check for vacuum leaks. Old hoses like to crack!
                  Remember too, that over the years soot can build up on many emission components.

                    Ignition module was the culprit, fixed now! A late thanks to all who helped here.
