My daughter has a 2020 crf110. I turned the key on today and the fuel pump ran as usual but instead of shutting off after about 5 seconds it continued to run the whole time the key was on (and the bike wasn't started). The bike runs fine and even shuts off with the bank angle sensor the only problem is the pump runs constantly. From your wiring diagram that you provide i see no fuel pump relay (that might be stuck) it seems to come right out of the ecm. Is there something that could be forcing the pump to run constantly?
