Stop in for a cup of coffee

so spark occurring between towers? Im stumped.
Dave mentioned engine ground.
Ohm the coil wire? Rule of thumb
Max 1000 per foot.

Iffn it was me,which its not i would pull #1 plug. Roll it over to top of compression stroke and set crank at 0 degrees on timong mark. Pull cap and look at rotor. Is it pointing at #1 coil tower?
No?
Put cap back on,mark centre of #1 coil tower on distributor housing.
Pull cap and align mark on distributor housing with rotor.
Now you are close. Can turn distributor a couple degrees to advance if you like, but should fire as is.
Driver side front is #1.odd bank.
