hey got a b16 installed in my 91 cx, the ecu is fine, it was with the engine in an old rotten crx, so i know its fine, i think they wired it wrong, id like to know where the injector wires plug into the ecu, the 4 injector wires and the one yellow i guess the one that controls the injectors, if someone could help me, id be very thankful

 

Hummm,, That sucks my 88 ef did the same thing and blown my motor! Hydro locked the bottom with fuel wow right and then blow my rods 3 of them as i pulled out the toll plaza cause it loaded wit fuel at the stop. Anyway dude, I know you said your ecu if good BUT what does a little diag hurt, back probe your harness fuel injector output pins out wit it plugged into the ecu Key on engine off and see what you got con. 5v? or 5v then out? next fire her up and and see what you got at the inject you can feel in injector pulse and here it if not well you might have a issue with the injector driver in the ecu ,sometimes they ground themselves out. LASTLY !! try a differnt ecu man. Holp this helped a little, o yea I HEART HATERS

 

what injectors?? obd0 obd1??, u should have a resistor box obd0, and no box for obd1, that all injector ground go to and 1 ground wire come from injector go to ecu, but here the pin out for injectors
A1- inj 1 A7 inj4 A3-inj2 A5 inj3. (a2/a3)gnd.
