Evasive Motorsports Obd0 --> Obd1 conversion harness
H-T seller Obd0 --> Obd1 dizzy harness all wires checked

Car cranks, No Codes, Fuel Pump turns on, Injectors click.

But I have no spark.

Are there any differences between an HF harness and a SI harness?

I'm stumped at this point.

 

Can the conversion harness be bad?

 

well if your car is turning on meaning everything is go till you crank it. couldnt be the harness but its not something i wouldnt think about though. you might want to check the igniters in all you dizzys, and check coils. they may have worked at one time like when you tested them but there electronic componets and will fail when they fail. you need to do a voltage test on the coil and igniter. oh and just for kicks check the plug wire you may have a open in them honda plug wires are know for falling apart inside.

 

try switching the 2 white wires on the dizzy and see what happens

 

I tried switching the 2 white wires. Nothing happened. Still no spark.
