Default 7 wont start INH

im dealing with a flood because we tried to use an intake straight onto the stock air hose replacing the mass air sensor turned it on, fired up then shut right off with the sensor off and no input signal to the comp telling it to give it gas it shut right off it was being given gas manually but not correctly i think and possibly flooded it. so we put everything back *does the "throttle plate" in the sensor have to go in in same position it was when it came out in order to work right? continued to believe it was then flooded we removed the two bottom spark plugs and removed the eng comp relay the fuse the furthest in and cranked it 10 to 15 seconds. to blow out the flood *nothing spat out, then put ATF in both bottom spark plug holes, put the spark plugs back in and cranked it with the eng comp relay still out and fouled out the spark plugs with the ATF. put the relay back in it still wouldnt start because the fouling we went and bought new spark plugs the right ones L and T, put more ATF in in the holes put the plugs in *wrong probably flooding it again so i took them back out cranked it with the eng comp relay back out and still nothing spat out and now or since removing and replacing the mass air sensor we have no spark

Why would you even try to start a RX7 w/o the airflow meter? It could possibly be flooded still, but who knows what else could have happened.

Did you mess with the Crank Angle Sensor at all? Stop adding all that ATF, will not cure anything. And please try to phrase your posts properly. It is hard understanding what you are saying when your paragraph has no punctuations what so ever.

Default phuc phrasing

phrasing would be me not getting into detail about what i did. i got into detail the best i could. i hope it wasnt to hard to follow along. i didnt touch the crank sensor at all. just the mass air flow sensor. diconnected and reconnected it. delt with the flooding 3 times in a row. even bought new plugs. and now theres no spark so where should i look for something wrong and the cause of the no spark.

sorry for expressing my frustration

The CAS tells the computer when to fire the coils. I would start there & also check all your fuses. Underhood & in the car.

Try another AFM and see what the car does.
