So for a couple of months now my 1983 280zx has been having a cold start problem. Every time I start my car it has a very bad cold start issue. The car will crank and crank and crank till finally the car sputters into life, after that the car runs fine but it is really ruining the battery to start like this. I only start it every once in a while but it happens every time. My prediction is that the cold start valve is not working but any ideas would be great
