1989 5.0 convertible has been sitting for two years outside. I put a new starter in because that was the reason the car wasn't driven.
Cranked the engine over just fine but now no spark. What is a likely reason the spark has disappeared? How do I go forward in testing? Can I check voltage at the coil and if so which terminal is supposed to be hot? Distributer looks fine. No water or condensation all clean and dry. Ignition switch? What do you all think is likely to do this from just sitting.

It may be too late but, and not related to 'no spark' condition, did you check the condition of the fuel/tank before cranking the engine? Todays or in your case, 'yesterday's ' fuel can and do cause issues with filters and injectors when left dormant for a long time.

Well, no. But the no spark issue is clearly a big problem so that is my first concern. Thanks for the fuel tip.

The car was outside you say, did the interior get alot of moisture in it?
I assume the engine compartment did?
