i would first try re-grounding the ECU to the body. i would second try a different ECU to see if it fires.

Thanks. I will check the grounding of my orange box. When I put it on last year I sanded the paint off the rear firewall and screwed it directly onto the bare metal. But maybe it has loosened or something...

Also - I do have a spare ECU (regular old metal/chrome box) that I can try.
