Well, im lookin to buy this '84 Camaro RS, the problem is, it doesnt start. The alternator turns, but the guy im buyin it from said there is no spark to start it. He said it is ether the computer or the ignition. He had a problem witht he ignition before, and replaced the computer and ignition, and it hasnt been right since.

Would anyone know of the problem if it isnt that?? Or if it is the ignition and computer, how much would it cost to fix??
