I will check the sensor. I'll be surprised if that is the problem. Only 400 miles on this motor.

When you say you have power with key 'on' do you have power when the key is in the 'crank' position?

On a side note, would anyone be interested in my do-it-yourself failed harness?
I think I'm going to throw in the towel.

Did you make sure it's plugged in?

crank sensor plugged in, taken out and re-plugged in.

Put a meter on the constant 12v, it reads 12v in crank and run.
Put a meter on the switched 12v, they read 12v in crank and run.

I must have missed or broken a wire somewhere in the harness.

DBW throttle blade is also unresponsive.

Thanks for the help so far!

When I was rewiring my harness I had a similar issue, pull the plug covers off and make sure all your pins are fully seated in the plug.
