Help....I have a 1978 280z that I have put a 1981 280zx turbo engine in,  I have the 81 wire harness,ECU, Mass air flow and such.  Problem is I cant get  spark to coil or spark plugs.  When I turn engine over and have coil wire grounded to body it will spark 1 time and that's is it.  have new coil , another used igniter and the CAS that came with engine,  Used wire instructions from hybrid,,,bunblebee z I think , have power to fuel pump injectors just no spark, have green light on at ecu.  I am at a point to put 78 wire harness back in and just run it as a add on turbo engine or get a 82 distributor and shaft and swap.  any suggestions would be appreciated
