obd2 b20b into 00 integra injector prob
Ive searched this and found all kinds of crap any help would be awesome. I swaped my 2000 integra with a jdm b20b i have all the obd2 stuff the injectors, distributer, and computer and i cant seem to get the injectors to fire i have fuel pressure, spark but the injectors dont fire. What could be the problem what in obd2 cars causes the injectors not to fire.

just out of curiosity did you use your integra injectors or was it even possible to use the b20b injectors?

Please clarify regarding power to the injectors... Is there a steady 12 volts on the battery side of the injectors (i.e. yellow/blk)? It is fed from fuse 31 (15A) in the under-hood box, through the yellow/white to the main relay, and then directly to the inectors.
If there is 12V there, then (harder) can you tell if the ECU is pulling the low side (blue) of the injectors down when it's time to fire? You could check continuity between the injector connectors and the ECU pins A1 (inj4), A2 (inj3), A3 (inj2) and A4 (inj1); in case there was a wiring mix-up or connector problem.
