Your fuel pump is going bad but you need to find out what's making your fuel pump bad. It could be something in the line making the fuel pump work extra hard or could be the line itself could be smaller than what it should be. If you gonna replace the fuel pump, the best way around that is to buy a whole gas tank from a salvage yard (taking a chance but fuel pump will be included) so you won't risk contamination in your gas tank.

What causes a loud whining noise?


Power steering pump, check the fluid level and if good check for clean red fluid no burnt smell. Other then that tensioner pulleys usually make more of a screeching noise.

Loud whining noise


A loud whining noise is indicative of either a faulty, or loose engine belt, a faulty bearing on one of the engines pulleys, or the power steering pump being low on fluid, or a faulty power steering pulley bearing.

Turing the steering wheel to the left or the right it makes a loud moaning and grining noise.please help thankes


Check the power steering fluid. located at the front of the engine where the belt is. if it low fill it to the mark on the stick/lid. if the noise is still ther after a while then you will need at minimum a new pump. you will need to have the system check for leaks.

1996 Geo Prizm power steering noise


Hi:
If you have been loosing fluid for some time, and running the car with low fluid in the power steering pump, then the pump is most likely worn and causing your noise. Do you know where your leak is? You might need just a power steering hose, but no matter what, your power steering pump is the most likely cause of your noise!

Power steering leak making loud buzzing sound more loud when turning


The power steering leak is creating bubbles in your power steering pump which gets strained more when turning, which causes it to be louder when turning. If you know where your leak is, then fix that, then try to bleed your ps system by filling up with the cap off the resevoir and turning the steering wheel max left to max left with trans fluid. if the noise is still there then your ps pump needs to be replaced along with the ps vsv located on the side of the pump.

My 1994 Intrepid recently began to make a different sound when i rev the engine. It is a high pitched squeal, it sounds like a go-cart. The steering wheel also makes a loud grinding sound when i turn it.


check your power steering fluid and pump, also these units have a problem with the rack and pinion unit, but start at the power steering fluid resovior and look for leaks, low fluid will cause the pump to starve for fluid cause irrepairable damage and noise as well... please rate my help, thanks
