I've been searching but couldn't manage to find anything. My question is, how much resistance should a good ignition coil read on a 5.5 gen? Thanks

Pin 2 and 3 should read anything other than 0 iirc.

Well here's my predicament... I bought a set of new aftermarket, not OEM coils. I tested each one, and they were all just about:
+1,-2= 1.10
-1,+2= 1.10
+1,-3= 3.30
-1,+3= I
+2,-3= 3.30
-2,+3= I


Then I tested my old OEM coils, and the result were different:
+1,-2= 1.35
-1,+2= 1.35
+1,-3= 8.30
-1,+3= I
+2,-3= 8.30
-2,+3= I


So, which resistance values are better? The OEM or aftermarket?

I don't know if this is an apples to apples comparison or not, but I got slightly different readings on my 2000 coils with approx 80K miles on them. I tested the 3 coils on the right bank, cyls 1, 3 and 5 and all had the same readings.

+1,-2= 1.53 K
-1,+2= 1.53 K
+1,-3= 7.8 meg
-1,+3= Infin
+2,-3= 1.53 K
-2,+3= 1.53 K

When I took these readings, there was nothing wrong with the car. I just did it to have the info.

I have seen the same. I measured some aftermarket coils I have and their values are always lower compared to my OEM coils. Just stick with OEM.
