1999 maxima ignition coil resistance results help

I got code P1320:
The front and rear coil results are:

(+)1 & (-)2 = inf
(-)1 &(+)2 = 2.5M to 2.7M ohms for all coils.


Does these results mean all 6 of my coils are bad?

I would think it means that a coil with infinity for resistance is open (a break in the coil winding). If you had 0 (zero) resistance it would be shorted (bad), and those with consistent resistance readings to each other would be OK. I don't know the spec for the coil resistance but you could Google the coil resistance.
