Question about 1989 Mazda RX-7
Its possible that the pressure valve relay is bad, you can try that. I had to replace one last year because it was doing the thing your talking about. I hope this helps. Alvin

well, with all that you have changed the only two possible things that are left PCM and the ECM....
Do you have an alarm system on this vehicle? If you purchased this car second hand it may have something that is inhibiting the engine from firing. From what you have told us here that would be where I would start looking.
I really hope this is helpfull

remove the rear seat cushion ,remove the fuel pump access cover ,start the engine and wait for engine to stall ,then turn the ignition off , the fuel system is now depressurized.

do you put your foot on the accelerator while cranking ???
rotors flood easily so dont be too worried if everything checks out
- voltage to coil packs are correct
- coil pack resistance is correct
- autochokes not jammed shut
- plugs are the correct type
- ht leads are measuring under 20k ohms
- what size fuel injectors are fitted...standard? a/market? impedence higher or lower than original? is cc rating higher tahn factory??

check the mas air flow sensor(is this the 6 cyl) the sensor has a problem with the nose piece inside not moving enough to tell the ecm the propper air flow for the cold start,also check throttle valve for dirt build up around it-if its a four cyl repost
