Default d15B8 into 91' STD starting issue

Recently bought a 91 DX hatch Auto 54k on the shell, everything was untouched bought from original owner.
Cam gear broke off and the car has been sitting for about a Year

I swapped the knuckles for Crx Si ones, pulled the engine and tranny.
bought a D15b8 from a 93 CX hatch, installed a DOHC ZC tranny(converted to 5 speed,Staying DPFI)

i wired it to make it think its in Park, and tried to start it today.
it cranks fine and is getting spark but its not getting fuel.

I thought it might be because I still have the Auto Ecu...Any help would be great,

Well, the ECU controls the fuel pump, so probably so. See this thread, on this page:

This was my 69th post, btw. WOO!!!

I fingered It out. I had to set the timing with the obd0 d15 distributor.
Because the Obd1 b8 distributor is slanted.

I'm stupid. thanks for helping hah
