Hello I am trying to install an 90 JDM DOHC ZC engine into a "federal' 1990 civic standard 4 speed. I have the PM7 ecu.

I verified the engine turned on and had good compression before I bought engine.

I used the instructions from
CIVIC4G.COM - Honda Civic 4th Generation (1988-1991) Forum ? View topic - DPFI to MPFI Conversion

I have spark. I put correct wiring with distributor.
But no start.. it cranks good.
The only variation I did was install all 4 injector wires (one per injector) to connect into ecu... and the other injector wiring goes to resistor box.
Could this varation cause the engine Not to turn on?
