Car will not start, has spark and fuel coming from the pump and the injectors are getting 12V. It will almost start with starter fluid but when I crank it without it seems like it isn't getting fuel. I have tried de-flooding the engine but nothing really came out of the spark plug holes even after I had cranked it a ton. Is it possible the CAS being not aligned would prevent it from being started?

The compression I did(with a regular compression tool) was 40psi on each face of the front rotor and 20psi on each face of the rear rotor. Even with bad compression it should start correct?

Wow your compression seems to be really low. That will definitely keep it from starting. You can try pouring a little MMO or 2 stroke in it to help build a little compression. But more then likely with numbers like that your engine is toast.

Yea I've tried premix, she tries to start and almost does but then just cranks over. If the engine is toast (pretty sure it was just needed some more opinions) Ill just sell it.

If your compression numbers are accurate then your engine is in need of a rebuild. Again, this is based on your tests being accurate.

If your compression numbers are that low, you need rebuild/ replace engine. I had an engine that had 60 psi on front and rear rotors when using a rent-a-tool from autozone. Constantly hard to start, use a eye dropper or equivalent to get some MMO (Marvel Mystery Oil) into spark plug holes, then the engine would fire up and I could get it to idle.

Not sure what your car/rx7 experience is but there is tons of info on this forum, just can take time to search for the answer your looking for. These cars take patience or money to pay someone to take care of it's problems for you.
Been on here for years and had several rx7's, and spent countless hours reading and researching. Worth it to me, but some not so much. Love my rx7s even though ive threatened to sell them a time or two lol.

Obvious first is to put in fresh plugs. Even deflooding an RX will still have issues if plugs are weak and then try a tow start to take pressure from your starter. If you start it up and then find it gives the same problems when next cold, engine compression is too low and you will have more flooding woes.
My first 3 cars were gen 1 and that was always the "sell" signal for me.
