Thomas,

 

    I had a somewhat similar situation.  My 91 13B engine got flooded badly when my fuel injection system died with all four injectors full open.  Liquid gasoline flooded the combustion chambers and flowed out the tail pipe. 

 

When next I attempted to start the engine I found that I had no compression.  Now in my case, it set for six weeks with the intake manifold off the engine before I attempted to start it again.  I managed by taking the exhaust off to free 5 of the six apex seals which were stuck in their grooves.  It appeared that the gasoline washed off all the oil and with the intake manifold off the apex seals/slots got enough moist air  to oxidized slightly - enough to cause the seals to stick in their groves. 

 

I could never get the sixth seal unstuck by poking through the exhaust port so finally had to take the engine apart.

 

However, in you case, a solution I have heard is to pour Automatic Transmission Fluid into the engine through the spark plug holes, replace the plugs and rotate the engine.  If that doesn't work you might get a brass or aluminum strip that you can push on the apex seals with and try pushing them into their slots.  As I said I got 5 of the 6 seals working again by that method.

 

But, in you case I think I would try the Automatic Transmission Fluid trick first.

 

Good Luck

Help, I made the mistake of starting my 91 rx 7 up, put it in the garage, shut it down. Thats it! went to start her up the next day, flooded! Pulled the plugs cleaned them up (almost new), Now it spins over with absollutly no compression!!!  (Yes I put the plugs back in) Ran great until now, Any suggestions???
