New fluids, new gas, injector/deposit cleaner, etc.
I'd recommend priming the engine by pulling power to the ignition coil or some other method of removing spark, and then getting a good battery and cranking the car, let the starter cool, crank again, etc. This builds oil pressure & gets oil moving thru the engine.
When the engine first starts you'll probably hear a lot of clatter from the top- end, thats the hydraulic lifters pumping up. It should go away once the car warms up.
Good luck, let us know if you have any problems. Also, welcome to TeamCapri!
