Ok, in the process of rebuilding my ninja 400 (track bike, not my first time taking a tank off a bike either)
Put new (used) fuel tank on bike since my stock tank is bashed in hard…
Put fuel in bike, primed system no start, but if I crank the bike the second I turn the key on, it’ll run till the “prime” cycle is over, it doesn’t turn the fuel pump on to keep the bike running…. What am I missing????

Coulda happened to anyone!
I knew it had to been something from today. So once I tossed the old tank back on and it was still doing it. I back tracked to the front end to make sure everything was right. And that’s when I looked at a plug and said “that don’t seem to be in a holder correctly”. Undid it and heard the ball bouncing inside it and wondered, flipped it and flipped the key and it started and kept running… hour of beating my head against a wall wondering what I did wrong 🤣
