Aww poor Z. She's telling you something is wrong with her.. Just follow her belches and moans. Make sure AFM (Air Flow Meter) is moving freely, Open TB (Throttle Body), Remove Intake to Turbo and make sure The turbo is not Seized (spray cleaner lie carb clean in there then vacuum Excess out givve the Compressor side by wastegate a couple taps (lightly) with a hammer and try with your finger to move the Turbine, remove ECU connectors and check for loose connector pins, clean battery Posts, Check the Fusable Links (little black box beside Battery), Check Relays in engine bay, check to hear if you hear Fuel pump working when you turn ignition to ON position (not RUN), Timing should be fine if never touched, HIT THE DASH HARD liek the Mellenium Falcon (Worked for Han Solo and my old Pulsar =-) ), ummmm Replace Fuel Filter for sure, if your able to remove injector Rail and soak in cleaner , hmmmm Mainly yeah Check major connections and then Clean her out FLush oil and give her a Go that should do her. Even my old 280zx Ran after being parked for 2 years on stail Gas not well but good enough to move her around hehe

Alright people, I will give it another try. I did read the manual book but I just keep hiting dead ends. I will give it another try.

 

 

My personal suggestion is that any 30 year old car that has set and not run in 14 years and sold for $200 would logically require a rebuild (or at least a serious investment in time by a knowledgeable repair person) to get it drivable.

 

Yes, drop the gas tank and inspect. Replace all hoses when re-installing. Test the fuel pump while you're back there. Moving forward to the engine bay, replace the fuel filter and associated hoses and install a $20 fuel pressure gauge after the filter (http://www.jegs.com/i/JEGS/555/41012/10002/-1 ) The gauge will tell you at a glance the real status of the fuel system.

 

Get a $16 volt meter and a $4 can of spray electrical contact cleaner. Start cleaning ALL electrical connections (AFM, dizzy and Temp probes). You can "borrow" a compression tester at AutoZone for free and that will tell you if you need to pull the head.

 

Download the REAL service manual at: http://www.xenons30.com/reference.html and there ARE NO DEAD ENDS when you follow the test flowcharts. Turn to page EF-33 and start diagnosing at the ECU main connector. It's invaluable and it's free.

 

Basically you have a serious electro-mechanical puzzle but there is no "one thing" you can do and the car will suddenly be fixed. Removing decades of abuse will be time consuming...
