No it feeds the o2 sensor and the fuel injectors and the coil.

Diagram shows 12v from fuel run relay connects directly to D terminal. May have a harness issue. Wire 751 also powers the O2 sensor.

If this has four wires at coil pack. Diagram shows terminals A B C D. A and B are the triggers from the ECU. C is ground. D Should be battery positive with key on. Up stream there should be a 6 pin connector. There are two 3300 ohm resistors that receive a 5 volt signal from the ECU the come out to the AB wires on the coil pack. The battery positive feed comes from the fuel/run relay in the PDM.
