Mine sat for 5 years due to previous owner, a friend of mine - We changed DME, flushed fuel lines, flushed brake lines, flushed clutch lines, new h2o pump, thermostat, timing and balance belts, oil change, transaxle drain and fill, new battery, new fuel filter, belt tensioner, plugs, flushed power steering, and new tires.
Mine was unusual as the owner parked it due to unknown problem then passed away. Found out unknown problem was pinion bearing..
Since startup and driving, having now to replace fuel sending unit and rebuild broken odometer and lost a clamp on coolant line, so replacing every coolant hose now.
Check any rubber under the hood.
