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.

i recently had the same problem develop. i would turn the key and it would not fire until the key was on its way back to the start position. i would crank it a few times , then it would start. i was thinking it was a fuel problem. it gradually got worse until it would not start at all. i pulled the ECU box off, stuck a new one on there, it fired and ran immediately. then a couple days later, it happened again. im thinking WTH? i pulled the ECU off, took a flap disc to the box mounting tabs and the fender apron where the ECU mounts and sanded all the surfaces to bare metal. i re-mounted the box, it has been working flawlessly for 2 weeks now.

it was a combination of the ECU going bad coupled with a bad ground
