I installed MSD 6A unit & 8920 tach adapt To my 240z with 79 280zx engine. as per instructions. the white tach output lead from 8920 is not hooked up.car has factory tach,but is dead.Engine fires, but won't run (idle) do i have the wrong tach adapter,or should i run system thur stk.ignition E12-80.Replaced 3 of these in the last 4 months' Car ran great for 3+ years.

msd6a wired with 8920 tach adapt. to my 280zx power 240Z fire's ,but will not run (Idle)white tach-output not installed,do I have to connect this so the ecu can trigger & run EFI. Spark yes! Fuel & spark in Start mod, yes! ! fuel & spark in run mod,yes. I have removed E12-80 ign.mod.Trying to -get engine to run only on MSD ignition Real world help ???? mag pick-up Green & red Msd violet & green. GRN 2 RED, VIOLET 2 GREEN polarity correct YES ?

early SU tend to run rich @ idle, throttle chamber cleaning & inspection,& fairly easy adjustment's they should run well, but the air pump is (really)the only clean-air Act. that would help! Install a 3-way cat.???? 12yr.vet@Midas .exhaust can't in and of it's self change HC/CO "fumes"
