Just this morning I began to hear an intermittent whine (repeats whining for a half a second, no whine for half a second) from the back of my car. I hear the whine while the engine is running (stopped or driving). I opened my trunk and listened and the noise was the loudest right above the fuel pump access hole. My fuel economy is at about 13mpg and car idles at little ruff and will sometimes completely lose power (but not stall) for brief moments during acceleration. Last week i had the same problem but i didnt have the whining noise, and I filled up on gas and the problem went away. I ran STP fuel treatment figuring that i had some junk in my fuel lines. Is this whine coming from my Fuel Pump/Fuel Level Sender area calling for a new Fuel Pump? Lowell? Winfred?
