It shouldn't be too big a job to at least get the motor running again. I would start by removing all of the fuel from the gas tank and wiping it out. Put a gallon in and run the fuel pump by jumping the RPM relay or just turning the key on and off a few times. Now remove that fuel, wipe out again and put 2-3 gallons of fresh fuel in. With a fully charged battery it should start up. The O2 sensor may have to be replaced. Things are never this easy so expect many parts to be deteriorated or missing especially in the fuel tank. Worst case may require removing and cleaning or replacing the spark plugs. In any case buying a "D" that isn't running is buying a "parts" car as until you get it to run you really don't know what it will take to get it running. David Teitelbaum vin 10757
