R1100S will not start.

[Wheaty]

The bike has been laid up for 18 months,brand new battery,no noises
when ignition key is turned,thought I'd cracked when I remembered
the side stand but no joy.

Fuses would be a good place to start. I assume that the dash lights are on?

Engine kill switch ?

[Mister C (Marsh)]

Sorry for asking but did you charge the battery?

Dont wanna scare you but after 18 months sat, who knows, I know somebody who found that most of his wiring loom had been eaten by critters after a similar period in an old garage. But, was the fuel stabilised before storage, if not the crap they call fuel these days could have turned into sludge in a lot of places including the fuel pump.

No offense Eyore

Ok.

Before running the bike, make sure the inlet tract is clear. My Daytona had a mouse nest in the airbox.

Can you turn the engine pushing the bike in gear (plugs out).

With the new battery in, does the fuel pump cycle and dash lights illuminate.

Is the kill switch set to run?

Yes looks like fuse problem... Everything else seems to be right

[Steptoe]

Start with the simple things before it turns into a guessing game.

Can you hear the fuel pump prime when you turn the ignition on ?

The last two winters I have had the same problem. Both times sorted by putting some 98 ron in the tank and giving the bike a good shake.

Try this before wasting time and money going down any of the other routes. Petrol these days is crap!

To me, it sounds like an electrical problem. With: “no noises when ignition key is turned”, I think OP means that the fuel pump is not making the buzzing sound it’s supposed to do.
If kill switch is OFF then it won’t do it, so that a good thing to check. Fuses next. From there on, regular troubleshooting. I’d check if the fuel pump is still alive by overriding the system by feeding 12 V directly to it from the battery.

@skiddy boxers: fuel contains a bunch of different hydrocarbons, some more volatile than others. The most volatile parts are there mere to help cold starts. Problem is, if fuel is kept in a container vented to atmosphere, they escape, leaving the “heavier” parts in there, thus hard starting in the spring.
So in theory, your thinking is absolutely correct. A sip of fresh fuel will do the trick, and get the engine started.

But, in practice? Sorry, but I’m sceptical. Pouring fresh fuel in the tank, and shaking the bike a bit doesn’t do the trick. How much “old” fuel is there in the fuel lines, and in the filter?
You’d probably have to crank the engine on the starter motor all day before you get fresh, good new fuel to the engine. Sorry.

I can only speak from experience. It's worked for me the last two years

I did miss the bit about no noises though so, yes it is probably an electrical problem.

Maybe the old and new fuels blend fairly quickly, i don’t know.

Anyway, though a bit more on this. I’m sure there’s a fuel pump relay in there somewhere. So if the fuel pump is shot, you should still hear the relay click when ignition is turned on. If no click, then it’s something else that’s not working.
