If you are talking about the fuel gauge moving on its own or when the vehicle comes to a stops this is controlled by the fuel level sensor it consists of a float, a wire float arm, and a ceramic resistor card.
The position of the float arm indicates the fuel level. The fuel level sensor contains a variable resistor which changes resistance in correspondence with the amount of fuel in the fuel tank.
If after you have scanned the vehicles computer and find no problems then to correct this you will need to replace the complete fuel pump, it only comes as complete unit...
this is called the lower switch
You need all sensors it was designed and built with.
I have a 2002 Olds Silhouette and had to replace the head gasket set 2 years ago. It raun around $1,700.00
Fuel tank comes in 20 and 25 US gallon.
It should have a bleeder screw on top of the thermostat housing.
Believe it or not..a semi pointed envelope opener works like a dream!
It's probably a problem with your catalytic converter.
All of my 2002 Silhouette outside lights had small leaks when I purchased the van used. I did not notice this when I bought it but shortly after, my rear lights all went out. I had to replace the whole assembly including the covers. I have not had any problems in the 4 years since I did that. After talking to several mechanics, I understand that is very common in the Silhouettes. Hope this helps.
I'm not sure if they changed anything between 2000 and 2002, but my 2000 window motor has 3 VERY breakable plastic clips that holds the motor in place around the gearbox.
On my 99 Silhouette, you open the hatch door, there is a half, to 3/4 circle that the tool from the jack fits in. Turn it, and the tire will come down. Depending on where you live, it might be rusty and sticky, so it won't want to come down very easy.
how do you fix security switch on a 2002 oldsmobile alero
