Yes seems like a tank/pump issue. The 87 had an electric carb, idk what it does bit I would check it. I counted 17 vacuum hoses from the carb, I would check all those (is in necessary?) But anyways, I would pour some tranny fluid down the cylinder chambers if it doesnt turn, then I would get that gas issue fixed. You may not even get to turn it over with the starter, I would replace it. If its 4x4 it's pretty easy just remove your inner fender and voila! Ots a matter of getting a 10' wrench for leverage and you're set.
