Dimitri,

All these are in the service manuals -see the home page for a free copy under the tech tab.

Be sure to check the grounding on your senders and grounding in general. Senders may also need adjustment and there is a procedure for that in the service manual.

With a bad ground, the gauge reads absolutely full no matter how much gas is in the tank . That's where I would start troubleshooting.

Yes, an open circuit if full scale full, and a short goes to empty. Higher the resistance, the fuller the tank...
