Just do your traditional pre start work
change oil, replace cracked hoses, replace antifreeze, remove plugs, shoot a little wd 40 in the cylinders, hand crank the engine, replace battery check battery cables check brake lines hard and rubber check wheell cylinders Blah blah blah .. Your big enemy will be bad gaskets from dry rot back in the 70's most were cork, they swell dried and cracked.
You have plenty of work to do to get a 20 year sitter back running properly but if you do it will pay off. the Cool factor of having a stock original pinto is something to be respected by many car enthusiasts like me. I haven't seen a Pinto with those stats in many many years and I visit alot of car shows and events each years, so much I am bored of them lately. A car like yours would excite me to see it in working order
Congrats on the unusual ride and best of luck bringing her back to life
If you had your heart set on an ecomod project then you will probably be able to sellthe Pinto for a rather good price if you find the right person. Not the best time to sell with the holidays though. I bought my wife a Cadillac last week for a steal of a price.
good luck
