I have a 1988 Rx7 Turbo II just recently bought and now it just won't stay on. First thought would always be vacuum leak but it doesn't seem like it now. I've resealed gaskets, cleaned injectors and even the throttle plates. My last resorts are now the BAC valve needs cleaning or replacing, the EGR diaphram is going bad or is bad and/or a bad ground. or even the AFM maybe. maybe its the fuel pump.

I'm so frustrated now but I understand the consequences of owning a rotary.
maybe someone can throw out solutions?

 

all of the stuff you mentioned have nothing to do with it being a rotary...

do you still have the thermowax on the throttle body? have you tried waiting for it to warm up before letting it idle?

 

problem is the car wont start... it'll crank and as soon as it seems to start it dies....

example: when a car runs "almost out of gas" it'll start then instantly die...

He has tried a lot of things but nothing. I thought maybe fuel pump but no, it comes on... he's been trubleshooting with me.

 

The fuel pump switch in the AFM can cause a problem like this. Fuel delivery on startup is different from when the engine is idling/revving. Will the engine run if the yellow fuel pump test connector is jumped?

 

the car runs if you stick a screwdriver into the afm flap just a bit. once you take it out it dies automatically. it stalls out by dropping idle quick.

 

Test/replace the AFM. Especially if it looks like someone may have opened it. Sometimes people adjust the spring tension, which basically ruins them. Cheap used AFMs can be found in the classified section; just be sure it's the right one.
