Ok Im having a pain in the *** time with the ignition output signal! I changed out the main relay, changed out the ecu for a known good one. I changed out my dizzy for a known working one. I checked for a loose connection at ecu and dizzy. I can hear the pump prime and the check engine light click when it goes off, but then when I try and turn it over the check engine light stays on and I get code 15. Its a 1990 crx hf with b18a1 swap. The car has not ran yet with this swap. I just bought the car and I had the motor sitting here in my shop.

 

Oh and I AM getting power to the dizzy through one white wire on the bigger plug and the plug with 2 wires Im gettin power also. OK UPDATE!! I checked the voltage inside the dizzy with the cap off and I am gettin power to the coil pack and out.

 

u try swappin the TWO white lookin wires that look tha same but they do diff things? on the round dizzy plugs? depin and swappn em around?

 

I already found my prob. none of the wires were matchin on the driverside harness plugs. swapped them and it is fine now thanks.
