Default dpfi to mpfi obd0 to obd1 help?

I wired up my 4 extra wires for my swap on the 88 crx and the engine was running before and now it isn't I only have stupid codes that don't amount to anything. I have done this swap so many times to other peoples cars but now I have this problem. The injectors are not pulsing, I am getting fire and it sounds like the car is off time but it isn't. I have tried everything and this is a very simple swap but something isn't adding up.
I checked the ground side of the injectors and I am not sure but I don't think that they should be grounded when the key is turned over. Are they ground side switched or not? I have hooked the grounds to the yellow black injector ground wires and hooked the grounds to A15 and still the same on both. OR are they powerside switched? also i am not getting power to the injectors? they dump fuel in sometime or another because the injectors get wet.

Ground side switched through the ECU. Power is applied to all injectors equally through the resistor box(or not if you're using OBD1 injectors)when key is in "on/run" position. The yellow/black wires are power wires.

ok figured out my problem besides were to stick the power wire on the injectors. I spliced to A13 for that then my car still didn't run though. I put a different distributor in it and now it runs. The dizzy wasn't throwing any codes and was firing.

Could have been firing at the wrong time.
