I have an '04 350z vert that has an intermittent no spark situation. It has a vortech supercharger kit. It sometimes starts and runs fine but will stall out randomly and not start back up. It has an ignition control box from vortech that is spliced into factory harness. It also has a recent new clutch.

So far I have replaced both cam sensors and crank sensor which did not seem to change anything.

Whats my next step?

 

Maybe the aftermarket ignition control box from vortech that is spliced into factory harness. Might have a poor connection.

 

I rewired some of the wiring but most of it looks good. I think it may be the box, not sure but its $550 from Split Second Tuning
