Connectors/pins have been visually checked at the ecm, transistor, and coil packs. This is a thinking out loud statement/question: Regarding the crank sensor, it appears to me it provides data only for the injectors and has no direct influence on the coils? As for the camshaft sensor, same for it however, an outside source schematic I Have shows the black wire connected from the transistor to the coil packs originates from the camshaft sensor. It also goes to the fuel injection relay.
