Is the engine turning over with the key in the start position? If the engine is not spinning over and you hear a whining noise, the starter is not engaging the flywheel. If the engine is turning over with the starter engaged, the engine has most likely jumped time that creates low or no compression which results in the whining noise.
Your ignition switch is going bad. The strange noise is the starter remaining engaged and locked to the flywheel. Your best bet is to have the starter tested at your local auto parts store, to deduce that it is not, in fact, your starter.
Without knowing where the sound is coming from, theres no way to know if it is important. Is it possible the noise is the ac clutch, and the ac compressor is locking up and killing the engine ?
low on fluid!!!!
thats why its HUNTING !! & the whine is the pump !
Check it for burnt smell & disclouration!
as that could indicate burnt clutches & or bands!
Cheers Rob.
I had the same whining noise, but after a minute or two it would go away. It turned out to be my water pump. It wouldnt turn first thing in the morning and the belt was just running through the pulley, (causing the whining noise). This may not be your problem, but it is easy to check. Just pop your hood and see if the fan is turning.
