Fuel pump or ECM

[stevenp0827]

Bike stalled. FI Flashing. pulled code C41. replaced FP relay. still codes out. could the Fuel pump be bad?,  The book says it could be the ECM ?  Bike was stumbling badly on acceleration and sometimes stalling while idleing before this happened? any help from the experts?
Thanks

Getting pump noise for 2-3 sec when first powering up?

If not pop the fuel tank up, and put a test lamp or meter on the pump (might have to find out which wires what).

Turn on ign, no pump power maby ECU, solid 12V maby pump.

If you are getting the normal pump niose on ign on its possible the pump may be running but failing pressure wise, youd need a pressure test on the rail for that.

Not a real cleaver answer I know but checking the volts if the pump aint running is a quick check that might point you in the right direction.

Cheers

I was gonna make the same suggestion of the fuel pump...You may also want to check your plugs...I had a similar problem replaced plugs and road out...
