I wouldn't play with the SAM, except as a last resort. It can be easily damaged if you short somethimg or put voltage in the wrong place. Then you're screwed.

Have you had your charging/electrical system checked? These symptoms point to a alternator or voltage regulator failure.

That wining sound isn't the fuel pump. It's a pump related to the emissions contol system. I think it is called the secondary air bypass pump. It usually runs for about 30 seconds when you first start the car.

A other possibility is that the throttle body is stuck closed.

Check the wire harmess at the throttle body. You will see that wires make an almost 180° bend before entering the connector. The wires can wear through and break or short together.
