Hi I have a mazda rx7 85 gls se and it wont start what should I do

What should I do if my mazda rx7 85 wont start what should I do

Yea it turns over but wont start yea it been sitting for 1 year

Ok first thing is to get all the old gas out of it. Then I would remove the spark plugs and turn engine over a few times to blow the old gas out of cylinders. Check, clean and or replace the spark plugs. Also good idea to undo fuel line at engine and let fuel pump pump old gas out of the line. Replace fuel filter also. Condensation builds up in fuel tanks when they have set for so long. Must get it out and replace with good gas.
