If the fuel pump is not getting power, first check the fuse on the side of the control box. Make sure it is not blown.

If the fuse is good, and you are still not getting power, the controller is bad. The pump is powered directly by the controller.

The fuse is good and it will send power to the pump when ever it is in a good mood.
Do you know the part number for the controller on mine

It is now running till it warms up then shuts off and not sending power to the fuel pump. But fuel pump is good and so is the fuse would you be almost certain it is the controller
