So I am getting no spark on any coil connected to the front pistons harness. I have swapped coils, checked the voltages and ground while running. Getting ground on black and 12v on the other 2 wires via a test light that pokes in the wires. I cleaned the connector and verified it is passing ground and voltage to the pins in the connector. What am I missing? I am getting the same readings on all 4 cylinders but the front simply won't spark. I can take the same coil out and plug it into a different location and it sparks. Seriously confused.
