Swapped coil across banks,ran an overlay on the control circuit and neither worked.
Re-ohmed all the wires again,checked with test light and meter and nothing.
Decided to swap coil harness since only ran overlay to the coil harness connector.
Found harness pinched when i pulled it,swapped to other bank and problem gone.
So swapped in a different coil harness and all is good now.
Had to bail cause it was 25* in his shop and had some stuff to do,tomorrow i'll get back on tuning it.
Thanks for suggestions mark.
