Folks-
I put in fresh gas (93), new battery, switch on ignition, headlight comes on, tach and speedo do their dance, idiot lights go through their paces, but don't hear fuel pump (I can  hear the pump on my 07 Multi 1100), engine cranks over happily, but won't start.
I swapped the two relays, but no change.
1- Is my assumption correct that there are only two relays?
2- As a sanity check, I'd like to get power to the pump directly; which two pins in the connector are for the pump?
3- Any way to repair/clean pump?  Bike's not been started in at least a year and I'm wondering if the pump is gummed up...
Something I'm missing here?
Any trouble-shooting ideas or suggestions are welcome.
Thanks in advance,

Peter

With your multimeter check for voltage getting to the fuel pump and sender units.
Iirc, there have been cases of the wires to the pump breaking where they enter via the sending unit. I dont recall which models, but seemed more frequently the problem than pump failures.

Use the search function because this topic has occurred a few times with wiring issues. There may even be a link to a wiring schematic.
Replacing an in tank filter will let you check the pump and internal hoses which can perish.

Someone else with more knowledge of your injected model will answer soon.
Cheers.
