Sounds like maybe the PCM. That's what grounds the circuit. When the engine is cranking or running: The pickup in the Distributor provides the signal input through the Ignition Control Module to the Powertrain Control Module (PCM), which returns a Signal to the Ignition Control Module. The Ignition Control Module switches current on and off in the primary circuit of the Ignition Coil, according to the signal from the PCM.
