Hi,
You have me a bit confused. I thought there was power to the pump. Is that correct?
As far as a toggle switch, I would not recommend it. If there is an accident, the pump will not stop pumping fuel. That isn't a good thing.
Do me a favor. Check to make sure the ASD (auto shut down) relay is good. I attached a pic below of it's location. Also, check fuse 49 in the same box.
Let me know. You may have a faulty integrated power module (IPM). They have several connectors filled with tiny pins that corrode, break, and so on.
