D to B Swap on 98 civic hatchy

Base model hatchy with y7 pre-cat from fact

B16 was a bit of a hybrid unit
OBD2 bottom end
OBD1 head
Used a Y8 Harness from an EL (canadian civic sedan sold under acura)
Using an obd2 del sol ECU for a factory B16 - P30 unit

Problem - fuel injectors do NOTHING. No ground pulsing from ECU

Continuity from injectors to ECU plug. Checked - A-OK
Fuel Pressure was A-OK
Pulsed injectors manually- A-OK

Wondering if ECU was buggerd so I used an OBD2 to 1 harness and then an OBD1 P30 del sol ecu that I KNOW works. still same issue.

SO, what does the ECU look at to trigger the injectors, the crank sensor or something else?

The bottom end of the B16 is obd2 and has a crank pos sensor on the oil pump that is plugged into the harness.

I am using a xenocron dizzy conversion harness to use an obd1 dizzy.

Where do I go from here. I am a little stumped here and I need this thing running so I can go home!!!!

Thanks in advance.

rick_rabies, thanks for the response but it wasn't a relay problem or an issue with the fuel pump. It primed continuously up until the battery voltage got too low from cranking. Just for some reason the injectors never fired.

To be honest I never found a solution, I decided the harness was an issue and just added VTEC, knock, iacv mod and extended the harness that came with the D16Y7 I pulled out of the car. It fired up right away on the first crank.

Well anyways, another problem solved. Just a little bit of extra work.
