Re: Fuel pump cut off
When you turn the key on and don't start the engine, and the fuel pump runs for 3 seconds or so, the PCM is shutting off the fuel pump. I have never seen one fail ad just keep the pump on all the time. Other than that, you would have to kill the engine somehow to prove it to yourself, so blocking off all the air to the throttle body should do it if you're so inclined....
