Starting a long sitting engine.

My car sat for 20 years and this is what I did.
1) hooked up an electric pump to the fuel line in the engine compartment to drain all the old fuel. I use an old 5 gal gas can to collect the fuel.
2) Pour fresh fuel in the tank and again using the electric pump to get the fuel up to the front.
3) Change the oil including the filter.
4) Pull all the spark plugs and crank the engine with the starter to get oil pressure up.
5) Put the spark plugs back in and try to start the engine.
Mine started right up and the only problem I had was about 3 months later a freeze plug started to leak.
Good Luck.
