it is the fuel pump because it is located in gas tank normal sound
Hard to tell without hearing it. With engine running, open the hood and try to determine the area where the noise is coming from then repost info.
wheel bearing, gearbox or wind noise Supercharger?
Its could be the turbo your hearing...
Gas Lid not tight is the reason my eng. Light keeps coming on
It may be the Idler pulley. I used to have a 96 Breeze with a 2.0L 4cyl that made a whining noise. I thought something might be seriously wrong, but then i discovered it was just the Idler pulley making noise. I changed it-- no more noise.
Whining noise near belts had pulleys adjusted any idea what is causing this
It may be low of lube or a bearing may be defective. Have it inspected by a professional.
Previas have a history of a whining noise coming from the catalytic converter. There is a bracket inside the converter that when loose or has came apart creates the whining noise during acceleration. It especially is very pronouced during high speeds in the freeway. You might be in for an expensive cat converter replacement.
The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.
it may be you powersteering pump get in week even though some winding is normal
A whining noise in the transmission is usually an indication the transmission fluid is low. Check the transmission fluid and fill it to the recommended level.
Well without further analysis or information, a short answer would be that your engine is BROKEN.
