I have a 1991 honda civic dx with a d16y7 swap. I converted it from dpfi to mpfi I'm using a obdo distributor n obd1 injectors I bought a conversion harness from mono tech n I have spark from the Dizz but no pulse from the injectors. And yes the fuel pump turns on? Why am I not getting anything from my injectors. O n if your wondering wich ecu I'm using its a pr3. If any one can help me out i would be highly greatful for your help.

 

are you using an injector resistor box on the obd1 injectors? because "there's your problem"... otherwise it sounds like you need to check the conversion wiring for the injectors, because it is not right.
