1299s won’t start

Slipnslide · Apr 29, 2020

Hey all hope y’all are well
I have a 1299s that started up well. I stripped it down for painting. Had the ecu off to get to the plastic piece under it.
Had the tank off to paint.
Connected everything back carefully and now the bike won’t start up. No fault codes or errors on the dash
The bike cranks, there’s spark but there’s no fuel pump priming sound.
Seen some posts where they have a bent fuel pump pin but that’s not the case here.
I was wondering if removing the ecu and connecting it back set an electronic lock. I tried the pin code option thinking maybe that would open up any locks there.
any and all suggestions are appreciated. Stay safe!

First thing that comes to my mind is the ground underneath the seat.... its an easy connection to forget.

I've even sanded it down for better connectivity but thanks alot!
The injectors are not spraying

Check all your fuses.

Done that first but all are good. Thanks though!

Did you check them with a meter or just visually? Sometimes they may look ok, but in fact are not good. If you have a multimeter, I would pull the injector electrical plugs off, and then crank the bike over and check them to see the voltage is present at the input to the injectors. That would at least tell you the injectors are getting power to them. Should be simple to do.

I'll try that. Thanks
I just pulled them out and looked But will try your method. Hopefully it's something minor
