I’ve chased every wire from the handlebars to the Ecm found nothing,I’ve have replaced fuel pump,coil and system relay,starter relay ,i harve power at the relay ,blue wire 12volts,wh/black stripe wire 12 volts when I hit the switch ,green/tan stripe which goes to the Ecm has power the y/r wire witch powers the fuel pump and coil no power trace that wire witch goes in to another harness with mutipale wires Ibelieve that goes to the TSM .Any suggestions will be greatly appreciated thank you
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.
