After that length of time, all rubber hoses and tubes should be replaced, gasoline should be emptied and discarded, and all electrical connections should be cleaned and checked.

Crankshaft position sensor would be my guess.

Got to the above website before you do anything else. Steps 1-5 are a must then you can start testing components.

Anything, everything,   I'm not being mean, just 30 years is a long time and lots can happen. The other thing would be why was it parked, it wasn't parked just because. Also because it was parked outside who knows what and where rodents got to

Mine is 34 years old. I believe it sat for at least 2 years before I purchased it. The entire cavity below the filter in the air box was stuffed with a mouse nest.

I hauled mine out of a junkyard where it say for quite awhile. CPS was all that was needed to get it to run. But to get it to run and drive involved a lot more. 

Pull out every fuse one by one and inspect closely. Clean them off with a wire brush and reinstall. I had a bunch of electrical gremlins to chase just from minor corrosion.
