Speed sensor is slightly out of range. This is another test for the sensors .

When my DME relay went bad the car would occasionally start and run for a few seconds. I think a bad solder joint in the relay would occasionally conduct but then warm up and fail. I know you believe your DME relay is good but changing it out or putting in the jumper would take little effort and I'd sleep better at night.
Just sayin.......
