i just bought a 1973 240z for my first car. it turns over but doesnt start. it turns over really smooth but just wont fire. what should i do first to try to get it to start? it has original su carbs.

any help will be greatly appreciated.

A little more information/history would help. Like; Has it been sitting in a barn for 14 years. Do you have any experience with old cars? Etc.

To get any kind of response from an engine, you will need Spark, Fuel/air and compression. Basic things to start with are:

1. Does it have spark? Pull a spark plug and check it for spark while someone turns it over.

2. If it has spark. Spray starter fluid (Aerostart) down the air cleaner while someone tries to start it. If it fires, you have a fuel/carb problem.

If it has been sitting a long time, it could have a lot of junk and old fuel in the fuel system. The tank and fuel lines will need cleaning. The filter should be replaced. The carburetors will need attention too.

it was sitting for a year. i went to advance and bought starting fluid and that did the trick. she's running good. thank you anyways.
