Could be the electric fuel pump if so equipped. What area(s) of the car the the fuse control, that should give you a hint. Some cars have a fuel pump system that the pump kicks on and off to keep proper fuel pressure up in the fuel lines. If not working right will run battery down in a few days.

High pitched whine


The most common cause would be a defective power steering pump.

1999 Ford taurus. My car whines/hums when it starts up and becomes higher pitched when I accelerate or the rpms go up. Becomes lower pitched as the rpms go down.. Transmission?


no this is not the transmission, based on my experience it is most likely the power steering pump, if is the single most common source of this type of noise in any Ford

I have a 1996 Ford Explorer that has a vacuum or intake leak. I can hear a high pitched whistling sound that goes up and down with the throttle while going down the road. It also gets a low pitched hum...


best way to find a vac leak is get a can of engine start, with the engine running spray it around the intake but not into it, be carful not to get any on the exhaust. If there is a leak the engine revs will increase due to the engine start being sucked in.

It makes a high pitched whine at about 62 mph


Vacume line off of transmission won't alow high gear and at that speed the tranny starts screaming for relief. Find the vucume line and make sure its good and connected at both ends

Same problem: a high pitch whine after extended driving


Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).
