When I was 18, I owned a 1982 280zn/a. She was my pride and joy. I had bought her from a little mom and pop sales lot in Houston for $1,000. She had a fresh black paint job over the extensive body rust. T-tops(one was cracked), tan leather interior(cracked and torn to hell). She had a 2.8 ltr with a 5 speed trans. And to the point. One day I was driving down the road and all of a sudden she died on me. Without warning, no big boom or anything. Just quiet. After a few months of sitting at my grandparents house and me about ready to give up. I went out one last time just to go through a basic set of rules about engine performance. You know, Air,fuel, and fire. Suck,squeeze,bang,blow. Then i went through the car as a whole. Is it getting air, yes. Is it getting fuel? yes. What about spark? yes. So, what was my problem? I just started to play with things. wires, hoses, belts, ................... damm, did i feel stupid, i didnt have a alternator belt. Went to the store, paid my five bucks or so. Went back and installed it. jump started the very dead battery. she started right up and purred like a kitten. After that. I always checked my belts.
