I put a d16y7 with y8 head and z6 intake mani. It is all hooked up and everything in my ef9(89 civic hatch si). The wiring is all hooked up but it won't start I have a obd0 computer and wiring harness trying to run to this. Well I mean all of it is but what all do I need to do? It will turn over but not start. There is one ground not connected and one plug behind the intake mani that will not plug in. I do not know where to start. PLEASE HELP THANKS.

 

hey have the same problem with mine its an obd1, everything is hooked up right it just cranks over and it also sparks, but it has a really bad back fire wile i crank it, it just doesnt start, it seems to be that the injectors arent shooting fuel!!!!!

 

Hopefully its not the ECU

 

swap the 2 white wires on the 7 wire plug on the dizzy
also, you can't put a obd1 motor or in todubbled1's case a obd1 motor with a obd2 head in a obd0 car with the stock obd0 computer and expect it to run right.
you need a jumper harness and the y8 computer and alot of wiring fun

 

as long as you using all obd0 stuff it should run.that means ecu,wiring and dizzy.you will need to be using the obd0 injectors w/resistor box.i have done this with a z6 swap,and a vafc.it ran fine untill 6500rpms then i never could get the timming and fuel right.spend another 150 and go obd1.
