I have an ongoing problem with the gas gauge not reading correctly. When I fill the tank, the gauge doesn't read full until the 3rd or 4th time I start and drive it. Once the gauge gets down to 6 gallons, it doesn't move past that point. Is there a sending unit that could be causing this, or is it m...

It helps to remove the fuel pump access cover from the spare tire area and then you can get to it from the top and bottom. Also, if you go to the maintenance section of volvospeed.com, aka...

The '95 has an OBD-II port, and I read it with a scan tool, but there were no codes. Might I have to take it to a dealer?

Thanks for the reply!

Howdy guys, I just picked up a 95 glt sedan. It has a few problems, but I got it for really cheap, so I think I can get it all straight and still be ok. It has 2 issues: it will not go into reverse, and all the dash instruments are dead. The previous owner said these problems developed simultaneousl...
