If the fuse is OK, you may have a bad wire or some other problem between the pump and the DME harness. The DME communicates to the pump with a short digital signal to tell the pump how fast to run. With just power to the pump, it will run at a default slow speed. The DME signal then tells the module in the pump how fast it needs to run. There may be a fault on that line, a bad connector, or something else causing the communication to fail.
Hey thanks for the great help M3m5 will check power at the connector and report with findings !
