Default 91 crx dx 5spd dpfi to mpfi

heres my problem.......

91 crx d15b2???? i forget exactly... but i took z6 head (sohc vtec) and put on it. with a zex cam.....

still in the process of trying to get it running.
Took a obd1 b16 distributor and repined it to the stock harness. swapped the tps wires and swapped over the wires inside the car.
ran the 2 wires to the dizzy and have the 2 left over for 2 new injectors....following me

i hooked up the colored wires on the injector clips how they should go to the harness wires. the brown, blue , yellow, and red wires on the clips, to the Yellow,red,and 2 wires from the ecu i pinned. i think at b10 and b 12,,,,,,,b12 had a white wire already, so i cut it and spliced into it.....
anyway......

i have spark to my plugs....but no fuel.....

Btw.....i have a resistor box (green plug)....1 yellow wire. 4 red wires
1 of each red wire with stripe went to the red wire on inj. clip.

i get one fuel squirt on the initial key turn, but then NO inj. pulses on cranking the motor.......injectors are good. yes.............
i have rechecked wiring 500x's on the ecu and nothing seems to be working out.

i have tried using a p06 with obd0-1 harness
and my old obd0 crx si ecu... (forgot the model #)

still nothing. .... any takers?

the no.1 pick up and everything is in the same spot as a d series. and as normal, only 1 bolt hole lines up....but ive tried everything.....advancing and retarding.....no injector pulses.......

i can try and change the dizzy to a d series. what ya suggest? y7? y8? or break down and buy the z6?

i was gettin a code for crank position .which someone said will interfer with my injector pulses and pick up. so i went through the wires on the distributor and switched the wires. and got rid of that code. but still no squirt.....

Work your way from the pump forward.

Is the fuel pump priming? Do you have pressure at the rail?

Maybe your resistor box is junk.

the pump primes.and plenty of pressure to the rail. i got a regulator and its open all the way. the car ran fine. then i dropped off the head and changed it and now i have all these issues.

ive tried 2 different resis. boxes and nothing....... Confusing!,,,,,
