i just purchase a '89 rx-7 13b n/a can not get it to start up. has spark, and fuel. need help. cover is off of maf sensor at aftermarket air filter. possibly flooding cyl. :dunno: never worked on rotary before so any help on where to start would be appreciated.

If its flooding it will feel as though the motor makes no compression. To deflood remove all of the spark plugs and crank unplug the Crank Angle Sensor (CAS), crank till no more fuel exits the motor and re install everything.

You may want to try a new mass airflow sensor (MAF), its wierd that the cover would be off. Testing procedures for the MAF are in the Factory Service Manual (FSM), you will need a digital multi meter.

The Afm should only be disconnected by Undoing the Clip/Connector..If someone has Screwed with it by opening it Up from anywhere else,chances are it is Toast..get the "N" number off it..Post a Wtb in the sec Gen section

As misterstyx said, and read my post sing air flow meter not mass air flow sensor.
