Electrical problem
1992 Lexus LS 400 V8 Two Wheel Drive Automatic 140,00 miles

hello. when i turn my car off at night, and wake up the next morning to start, battery doesn't have a charge. when i put a new battery in and turn the car off i hear a sound thats constantly running under the hood and does not stop, at the top of the motor, near the traction control. sounds as if gas is running to the fuel injectors or air is pumping from somewhere. if you all have any ideas, can you please help.

thanks, wilson

may be some type of relay stuck open in that area. use a mechanic stethoscope to help you find what exactly is making the noise. if fuel was flowing then you would smell it easily and your car would smoke up white bad on starts.
