I recently got an 87 na. It used to be my aunts and she has gotten REALLY sick so she gave me the car but she has had it parked for about 5 years starting it only a couple of times a year for the first 3 years and never since. I've checked it over and it seems ok but it wont start, I've checked the ignition, fuel, and intake, there all good but it has no compression, my guess is the apex seals. Have any of you ever heard of the "ATF treatment" and if so how well does it work, and do you think it would solve my prob. Any info would be great! thanks all

 

before you try to start it you should replace all fluids in the car, check spark plugs and plug wires

something that will help you is pull off the air cleaner top and spray some starting fluid in there while cranking, if the car starts then it could be a bad fuel pump or a problem with the fuel system.
If it doesn't start then I would suggest you go to the faq and look for info on no start problems
