Try starting with some of the information on this page:
https://www.rx7club.com/1st-generation-specific-1979-1985-18/1st-gen-rx-7-faq-page-237777/
Read all of it if you can, but the ones about starting are a bit more than halfway down the page.

Sitting cars can have a world full of problems, but can be fun as hell to fix. Here's a great way to start:
Replace these things:
- Fuel, Air and Oil filters
- Oil
- Drain the Gas Tank and fill it with good gas. Sitting gas turns into a varnish-like substance
- Spark Plugs, Plug Wires, Distributor Cap and Rotor
- Battery
- Do a Coolant Flush, replace the thermostat and gasket.
- Some carb cleaner can help once you have it "basically" running.
Try to turn the engine by hand. If the main pulley turns freely, then you're good. IF it doesn't, read the "decarbonizing a rotary" article stickied at the top of the 1st gen section's page.
If the engine turns freely and you've replaced the above and it won't start, definitely check out Pele's "End of all no-start threads". An awesome piece of work if I do say so myself.
When you have it running, check your brakes before you go anywhere. Mine were in horrible shape and it was sitting under a tarp for 4 years.
If you have any other questions, feel free to post them. I've spent the last three years restoring a sitting rex. I've learned a hell of a lot, and enjoyed every minute of it. Read the FAQ at the top of the 1st gen section page, and check the archive for some cool stuff. When you've got a question, those two places often have the answer.

Oh.. and don't use Synthetic oil.
Well, use it in your transmission, and your rear differential, but not in your engine. This is a holy war here, and I don't want it to start up again in this thread, but non-synthetic is cheaper, it's more than fine to use in rotaries, and there's a chance (however slight) that using synthetic oil can cause problems if your Oil Metering Pump is still stock.
The Oil Metering Pump is an odd part that only rotaries have. It's purpose is to take minute amounts of oil from the oil pan and inject it into the intake along with the air/fuel. This is *necessary* to properly lubricate the apex seals. I'm not going to get into details, but suffice it to say that your car is DESIGNED to burn a bit of oil, so don't worry about a bit of blue smoke on startup. We all have it.
If you want more info, do a search on OMP or "Oil Metering Pump". Searches turn up tons of threads, but with a bit of patience you can find some good stuff.

Edit: and please PLEASE don't just do any old "ATF" treatment!! Read the "decarbonizing a rotary" article first!
