Default dpfi to mpfi conversion, car wont start

This is for a b16a into a crx dx 88, with odb-0

I have my injectors wired up straight to the ecu

A1 to injector 1
A3 to injector 2
A5 to injector 3
A7 to injector 4

Then i have the four red and black wires attatched the 4 red and black to the regulator.

The cranks over just wont start, I spray starter fluid inside the intake and it almost starts up for a second then just starts cranking again. So im thinking its a combustion problem, if anyone could help i would appreiciate it

Did you add CPS wires to the distributor?
Any ECU Trouble codes? (those usually point you in the right direction)

10 & 14 usually means you have the connectors for the EACV and IAT (Intake Air Temp) switched - EACV = Blue/yellow and black/yellow wires - IAT = red/yellow and green/white wires - 7 is TPS - did you swap the yellow/white and green/white wires? 6 is coolant temp sensor - is it connected? on end of head below distributor and has 2-wire connector with red/white and green/white wires - 4 is crank sensor in distributor - did you move the orange wire at the ECU from C1 to B10 and the white wire from C2 to B12?
