92 buick raodmaster fuel gauge not working

I haven't found a fuel gauge that didn't use a wire wound rheostat on the float arm in the tank to apply current to warm a bi-metal strip in the gauge. In my '89 Toyota van, my gauge would only work from 1/4 down. I had to take the tank out to work on the suspension and on removing the sender, I found the sliding contact loose on it's pivot and the coil coated with a white residue. With gentle tweaking and 600 wet-dry paper it works perfect. But I would first check if you are getting 12V to the sender on the tank. Keith L.

I have a JBL 6-disc changer2002 Camry. CDs won't eject. Matter fact when CD option is chosen CD player does not even work at all. Any helpful information would be greatly appreciated!

It sounds like you have a disc stuck and it's overriding any commands. I would put the key to acc. Then I would unplug the cd changer from the back of changer and after a min or 2 plug it back in as you hold down on the eject button
