I have a 280zx and sometimes after I drive it for a long time, it wont start up. It will turn over, but it takes about 10-15 seconds before it will actually run, but even then it doesn't sound like it should. when it does it, (when I start it), the temp guage reads in the upper range, near the hot end of it. Any suggestions???? I think it might have to do with the fact that my radiator might have a crack in it, and there fore is an effect of the loss of pressure inside the cooling system, because of a probable false reading on the temp guage, but I dont know. I'm going to get my radiator pressure tested so I dont know. Any help would be greatly appreciated as I want my car to run at its best. (Its a '79 280zx with 45000 original miles on it).
