obd1 b18b1 into 91 civic standard

[hondaracercrf3]

I have a 1991 honda civic i just put in a obd1 b18b1 with a p75 ecu
im using a obd0 b series harness but i switched out the distributor plugs to obd1
since im using a obd0 harness it only has a 1 wire o2...i need a 4 wire o2 so im just going to wire it straight to my ecu...
so im running without an o2 sensor...and it runs fine but the problem is..is that it is a bitch to start....you have to sit there and crank on it for a while...and it will start and die start and die....im also using single cam injectors with the obd0 clips....i was wondering if anybody knew that the problem would just be not having an o2 sensor and running obd0 clips with single injectors?? or would it be somthing else...
i really need some help please

you should be using the same injectors that go with your ecu, as far as I know.

what obd are the injectors? if there obd1 injectors you have to cut/solder the plug for the resistor box...
