Well the problem is gone. It was suggested to me that if the fuel lines were under pressure that the pump would not run. I was going to start bleeding the supply when it struck me that a non-working pump shouldn't allow the line to remain pressurized after an attempt to start. With the pump unplugged I cranked it over and lo/behold, she fired up and ran for about 10sec. I plugged the pump back in and she's been running great since.

The solution holds no logic for me but neither does most of the stuff on these new rolling computers.
