alternator? that's the only thing that even remotely makes sense to me. Since you are using power, I believe it still comes on.

1990_whitecomet

yea, i thought it was the alternator too.. i stuck my ear right next to it.. but heard nothing.. it was comming more from the inner motor, more of the center of the intake manifold..?? weird.. i don't really have a clue.. so im just asking you guys.. if anyone would know.?? cause im really stump too...

mine does that also. But only when i pull the engine fuse to unflood the car. I have no clue what it is. Never tried to track it down. Just put the engine fuse back in and all's well. ^_^

Fuel flowing through the rails in some cases, the BAC valve clicking rapidly in others.

Put your finger on a fuel rail and see if it is that. THen try the BAC valve.

Either is normal.

how can an alternator make noise with the car off?

fuel flowing through the rails.. huumm.. that makes some sense.. since it is comming from there too or arouond that area.. kOol, i'll onto that and come back and tell you guy if it is or not..i'll see but thanks, rotaryrecurrection.. it was just werid and was just wondering and wanted to know..
