When my coil went on the #1, the meatball at the counter where I got the coil told me the #1 plug was on the driver's side.
After changing it, and no difference, I learned the #1 was on the passenger's side.
I would also be looking into the connector plug that goes into the coil, and the wire leading to it. May be a short or bad wire that's not firing the coil.
