my rx7 wont run....why??
whats up people.... im fairly new to the world of rotary motors and knoweledge of them is very minimal..being that ive had all hondas in the past it alot harder for me to pick up on **** as easily as i would with a cylinder motor.....but heres my problem:
i just recently picked up a 1987 RX7 with the 13b non turbo rotary motor. i got the car for about $200. the guy that i bought the car from said that i was sitting for about 6 months before he last drove it. when i first went to go see the car and run it, it didnt start. i was cranking but it wouldnt start. i noticed that the battery, and the terminals were very corroded so i bought new a new battery and terminals as well as some ether carb cleaner. the next day i trued again to start the car with the new batter and the terminals and the car started! i was so happy but as soon as i took my foot off the clutch it turned off????..so i thought i might have had it in gear but it wasnt it was in neutral and it still shut off so i kept my foot on the clutch when i started it again and it started up but now the onyl way it would stay idling was if i kept my foot on the gas . i was like what the @#$ !?? how is it possible for the clutch to controll the engine idle?? and why isnt it idling on its own?? so basically i couldnt start the car unless both the clutch and gas was depressed even tho the car is fuel injected. so i tried to use my knoweledge of cylinder cars and figure it out. every car needs air,fuel, and spark to start so i kno it was gettin air and it was ovibously gettin spark or else it wouldnt have started but i didnt kno about the fuel....at this point i decided to spray some of the carb cleaner into the throttle body .now i know the car isnt carburated but the cleaner is pretty much made out of the same stuff as the starting fluid so i sprayed some of that into and i started and it started and idled for about 5 seconds and shut off . so i figured that i spray some more so i did and i tried to start it but then it didnt even start at all. i went back ot the store and bought some straight starting fluid (ether) and i sprayed it into the motor and it started again but for only 5 seconds and once again turned right off.i sprayed it again and now it dosent start at all...so im right back where i started.. i dont understand why it wont idle...did i spray too much starting fluid?? it was starting earlier and running as long as i kept my foot on the clutch and gas pedal but now it dosent even turn on at all..i went from running to starting, to nothing?? someone please hellp me out and point me in the right direction.

Welcome to joys of the rotary world. LoL.
You're problem sounds like Vac leeks or a possible blow rotor. What you're going to have to do is run a compression check (check out www.rotaryresurrection.com tech->compression check) and tell us what numbers you get.
After or before that, you're going to have to look for vac leeks. There are tons of tiny vacuum lines running around the the engine bay, and if one is leeking, you car won't run properly.
Also, it might be dirty spark plugs, lack of fuel, lack of air....It's all about the basics!
Be sure to look at the FAQ and download a copy of the Factory Service Manual, it's free and will help a lot.
Good luck!
