Could be a chunk of carbon in the engine, lodged on an apex and a port. Remove the starter and use a prybar to turn teh ring gear in the opposite direction, or try to push start the car, but use reverse. (Or push start the car by pushing it backwards and use a forward gear.... You get the idea...) If she doesn't turn backwards at all, it's rebuild time.

P.O.S. Racing

Sounds like a good candidate for the old Automatic Transmission treatment. If it seized due to carbon build up it may actually save the engine.

Don’t know all the particulars on doing this, but I’m sure someone out there could enlighten us.

Defiantly wouldn’t try to spin the engine until you get something in there to help it slip & slide.

I had my car do that to me once and I was told to spin the engine backwards to free it up. What I did was get someone in another car to push me forward, then I put the tranny in reverse and very VERY carefully let out the clutch. Once I felt the engine spin I put her in first gear and let out the clutch nice and slow and she fired right up.
Believe or not a nice chunk of carbon flew out of the muffler and right onto my friends windshield!

There's a detailed writeup of the ATF treatment at the Mazspeed website. (www.mazspeed.com). Then click "facts", then "ATF". I've never used it, but I've never heard anything bad about it, either.

Some group members have found in the past that if a car has been sitting for ages, the petrol turns to sludge, and can clog up the system. You might want to check that before you try turning it over, if it has been sitting for ages.

I am new to this list and this is my first post. my 84 GS has been stored on a farm for around 5 years. she has tree sap all over her and to my horror the rear window was broken around five weeks ago by a hail storm. Now I have it back and plan on fixing every thing. problem #1 the fuel filler neck shows a fair amount of rust and I fear for the condition of the fuel tank. how hard are they to remove? and has any one done this. #2 I have striped out nearly all of the interior due to the water damage form the broken window and replaced the window. but we had a thunderstorm last week and there was water in the spare tire well again. I can't figure out how the water is geting in. The window seal looks good. any ideas? and lastly, any general things to look out for/replace on a car that has been sitting for so long. Thanks in advance for any advice that you can give me in bringing my old car back form the dead. btw it only has 67,420 actual miles on the engine.

Redlance,
you should really start a new thread. Since this one looks solved, many of the experienced folks may be passing it over now.

Drain and replace all the fluids.
Get some penetrating oil in through the spark plug holes, use a socket wrench down by the pulleys and see if you can still spin the motor.

Don't wait for a rain to spot a leak. Dry her out, layout some newspaper and run a hose over her. Maybe that'll give you a clue as to where the water is coming in from.

Remove the storage bins and sound insulation and get down in the compartment to see if there is any rust by the rear fenders. I hear that this is a common place for rust.

Those are just general things. Welcome back to the RX7 world. Nice milage on that car! I look forward to hearing more about your progress. Good luck!!!
