The lower sensor.
I do hear the pump turn on. Am thinking you may be right about the hes sensor. Am just too much of a rookie to attempt that replacement. Is there a easy way to test the hes sensor and fuel pump. Hate to throw money at it to find out it was something different. I try a hot shot box to jump bike today to rule out battery but still no fire. I did remove the pump some from tank but stopped short when it didn't seem right. I reinstalled gasket and tighten back up with no P roblom with gasket lining up.
