Does the 01 Lexus is300 have a system or something that will turn off the fuel pump if it senses a lack of spark? They don’t have the roll over type switches that turn off the fuel system correct?

Pretty sure they do not have the roll-over protection fuel pump shutoff. It should prime the pump when you turn the key but it will not continue to pump fuel if the engine isn’t running.
