Hello all, I think this has been covered before, but I cannot seem to find a solution on any of the other post.  I have a 2022 CfMoto Cforce 400 with about 180 miles.  It was running perfectly fine and then all of a sudden the fuel pump will not prime on switch.  I have checked the FP relay, the FP fuse, and they are good.  There is no 12v getting to the fuel pump red wire (plug at the pump). 

I would like some help with this please.  I am mechanically inclined enough to replace anything on the unit, and to trace back issues.  I can't seem to fine a wiring diagram.  If anyone has had this issue on the 400/600/800 and found the solution please share!!!  Thanks in advance!!!

Here is the 2020 450/400 wiring diagram. I would think it would be very close to the 22. I believe the pressure regulator is in the pump so no power to it has to be a relay, connector or supply issue. Check your key switch and the kill switch.

Thank you for the response.  I will check the switches.  On these units, does the ignition coil / solenoid under the seat share circuitry with the fuel system??  Could this be a culprit also??  The fuel pump connector (red and blue wire) seems to be webbed into the main harness and I didn't want to have to un-tape the harness if I can help it.  How often are these red skill / start switches bad on these things?  Thanks again

You have the diagram. Just follow the path(s). Find where you do...and don't have power in the run position.
