Is it normal to have power to injector with key off?
Having power to the injector with the key off may be normal as most systems run the return side of the circuit through the ECU and no current flows in the circuit until the ECU commands the injector to turn on. Did you compare other injectors also to what you found on that one?
What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?

Why does my injector keep switching to ground?
They very likely switch ground as that’s actually easier to do, electronically. If you see power across the coil of that particular injector all the time, you may have a pinched wire that’s now shorted to ground, for instance. More than likely the driver in the computer for that injector has failed.

How to ensure fuel injectors are receiving the correct range?
Step 1: Turn the car on. Turn the key to the second (ON) position for this test. You want battery power flowing, but don’t want the engine running. Step 2: Set up DVOM to measure DC voltage. Use the lowest range possible if the meter doesn’t auto range.
