First of all, Welcome. Hands down, These are some of the best folks around for knowledge and resource information. You'll need to download the FSM and EFI bible here, http://www.classiczcars.com/files/category/4-manuals/ Those are going to help you the most on your new journey.
Also, check all of your vacuum hoses from the charcoal canister to everything on top of the manifold for leaks/cracks and rot. Also check the PCV hose on the bottom of the manifold. All of those are cheap and easy as well as necessary for a car that has been sitting for a long time. Fuel delivery is also a potential issue and can come from a variety of areas like rust in the tank for example. The more info you give, the better help you will receive. And pictures really help too, even if just to show off your Z.
