Open circuit - gauge will read full.Grounded circuit - the gauge will read empty. If it reads empty all the time - then the wire that goes to the sender is broken and/or grounded somewhere along its length to the fuel tank. run a jumper wire from bottom of the fuse box in the spot, all the way to top of sending unit on tank. disconnect old wire at both ends, and then turn on the key and observe guage. if not this, check guage itself for sticking.

    Oh man, I don't know if you're still a member here at fixya or not, but if so, and you get this... THANK YOU. I recently fixed a wiring issue related to the wire loom that runs everything from the back of car (i.e. brakelights/turn signals, fuel sensor wire, reverse lights, etc), and fixing this happened to also fix my fuel gauge which had been stuck at as-full-as-possible. I was trying to confirm whether it was coincidence or actually something which may have been related, and the bit of info "Open circuit - gauge will read full" is exactly what I needed to know. Thanks a bunch!

Power driver seat will not adjust forward or back.


My intuition tells me that the 6 way power seat track forward / reverse motor is bad. Sometimes you can replace just the one motor but most often a whole new power seat track is the only way to repair. It is not too bad to replace but the seat will have to be removed from the car and placed upside down to access the track assy. There are 2 bolts in the front of the seat and 2 bolts in the back of the seat that hold it down to the floorboard. Once it is loose you can rock the seat backwards to access and unplug the electrical connectors.
