Do you have a wiring diagram you can post here? Is the ecm triggering the relay coil? These usually have issues with the pump control (usually brought on by human error or as simple as dry solder joints). If you can post photos of inside the ecm on both sides of the board, we should be able to see it.

I would check the speed sensor . Its a major part of the fuel injection system.
