How do you check to see if a coil is good or bad on a 1995 Isuzu Rodeo 3.2 L V6 4x4 P.S. It has 3 coils on this coil pack.?

Hello, Jamison here, You need to remove the coil that is not working, You can test it with an OHM meter, You will need to have an idea of where it should be first, If you can not find this information, You can remove all 3 coils and test all of them, if one is bad You will know by the difference in resistance, If it turns out that they are prety close, It could be the ignition module, This type of PCM setup is sort of like haveing 3 different ignition systems. Most parts stores can NOT test coils for you, but most of them CAN test the ignition module. Good luck, Jamison.
