Keep in mind our pumps DO NOT run when the car is shutoff.... Its possible the SLK32 pump runs, but not the srt-6's. I tested by running a voltage meter from the pump connector to inside the car. The instant I shut the car off the voltage dropped to 0, theres no way the pump could've still been running.....

And on top of that when the car is running and the pump is running its not always possible to feel it with your hand. I never could.
