Re: Ignition Coil?

The coil plus comes from the ASD relay. The coil negative goes to the PCM and is triggered to ground.
Disconnect the coil, test the plus while cranking, if the voltage drops significantly you have an issue upstream from the coil. If it drops significantly connected on the plus side while cranking, you likely have a partial short in the coil.
Did you test the plus, minus, and high voltage side of the coil to ground?
