[Hybrid]

Hi Guys,

I've been wiring up my G16B sierra install and was hoping someone might be able to suggest what I'm doing wrong. Basically I'm getting no spark to the dizzy. I have the following:
- 12V at the coil
- 12V at the coil secondry out (the HT lead that goes to the dizzy) but no voltage spikes as it should while cranking, just the steady 12V
- 12V in to the ignitor
- Whilst cranking I get voltage pulses in the orange wire that runs from the ECU to the ignitor

Obviously I've got all the power there but the coil isn't triggering. What actually triggers the coil? At this stage the only wire I haven't routed and connected is the brown that runs from the radio noise supressor to the tacho.

Any help would be great guys as the wiring part of the transplant is getting a bit old......
