"check power into your ignition module(4 prong, intake)
check power out
if one side isnt working cause no power going into the module from the ecu, JUMP IT from a 12 volt source. Those coils are just a basic 12 volt setup. Make sure you put power into the module so the module can do whaterver its job is for the coil. You know, just keep the coil pluged in to the module add power to module.
You can even use the power from the other modules plug, cause up stream they share the same power supply anyway."
