Remove the cam sensor. The bottom of the cam sensor connects to the end of the cam, and the oil pump shaft. The gear around the bottom of the sensor shaft is driven by the cam, and the slot in the bottom drives the pump.
I cut the handle off a big long fat screwdriver and put that in the drill, but you can buy a tool that does the same thing. Basically you stick the slot of the screwdriver into the tip of the oil pump shaft where the cam sensor would normally go.
