Won’t stay running
So I have a 1989 rx7 convertible with the stock 13b fuel injected rotary. I’ve been having trouble keeping it running. I can get it to idle for a about 15 seconds then it stalls out. I replaced the fuel pump, fuel filter, the sending unit for the pump, the ecu, maf and map sensor. I tested the injectors and they r spraying. Everyone I’ve talked to has said fuel pump cuz it’ll idle then die still same issue. I also did the spark plugs, wires and ignition coils. When it idles it’ll back fire and blow some smoke out the exhaust before it dies. I can’t seem to figure out what’s going on or why it won’t stay running. Can someone give me some advice on where to go or what to do next ?

welcome to the board. 
does it matter if it's hot or cold? does it remain lit when you put your foot on gas?
with all the new pats you put on it, one thought is to check the compression, another is to start looking at sensors (TPS, BAC, etc).
also, PM a mod and have them move this out of the Build section.
