Was it prepared for long term "dead" storage when you parked it? Gas tank full, fresh oil and filter, engine running while you poured oil down the carburetor until the engine stopped, carburetor and fuel pump removed and stored separately in air tight bags? If so, remove the spark plugs and spray some engine fogging oil in the cylinders. Try turning the engine by hand. DON'T force it though!! If it will turn freely you're in business!! Drain the gas tank and add some fresh gas. Install the carburetor and a new fuel pump (if mechanical). Put in a new battery and spark plugs. Check the fluids and see if it'll fire up. If you didn't prepare the car for storage, you'll want to remove the gas tank and have it cleaned. There's probably condensation and rust in there. Have the carburetor rebuilt and blow out the fuel lines before trying to start it. A new fuel filter will be needed as well. Once you get it running, inspect the brake system very carefully and replace the tires, belts and hoses to insure that it's safe to drive. Anything rubber will be deteriorated from sitting. Especially the tires!! HTH. -Jim


Hello Trannyman. Thanks for the kind words! 18 years is a long time for a car to be sitting! -Jim
