I have a dohc zc in my 1990 civic I got everything in and wired up correctly I have injector pulse and everything seems to be doing what its supposed to except firing the plugs I replaced the ignitor and coil with a known good one and still no spark if someone has run into this before and can help it will be much appreciated.

 

first i would check the main fuses in the engine bay fuse box(the big fuses) check plugs and wires, cap and rotor. do all that then go from there. also check to see if your getting power to the dizzy, iforgot what 2 wires to check voltage between so if someone could add that.

 

is the ground wire from the harness connected to the thermostat housing?

 

what trim level are you swapping into? did you have to re-pin the dizzy connector? if so try swapping the 2 white wires.

 

its a dx and the harness I bought through a company in calif. so all I had to do was plug in and roll I am just wondering if the dizzy or the ecm might be bad its a pg7 ecu and the dizzy looks stock all I did was put a coil and ignitor in it . all the wiring per the compnay in calif. is right everything seems to be working but the firing part and well I kinda need that
