I would start at the tank. Remove it and clean it of old fuel after you remove the pump plate.

Next, inspect and replace the likely cracked rubber fuel lines making sure you use replacement lines that are submersible in gasoline (SAE 30R10 rating).

Next, replace the fuel filter.

Next, blow out all the vent lines noting their connections (don't reconnect wrong).

Refit the tank and fill with fresh fuel to which you add some fuel system cleaner (Techron is used by boxer owners). Energize the pump and determine if you have pressure at the injectors (43PSI).

Clean the injectors of old fuel and varnish. Replace the filter screens in the injector inlets. Refit the injectors insuring that the o-rings are secure.

Start the engine.

Report your success here.

maybe a stupid question

do you have an alarm on the bike ? I tried starting my GS after sitting awhile and forgot to turn off the alarm. Experienced same symptoms you describe. Turned off alarm and bike fired up.

First make sure you have fresh fuel in the tank. Based on the symptoms that you have: spark but no fuel at the injectors, here are some possibilities:

--no fuel pressure. disconnect return line going back to tank. press check valve on hose connected to fuel distributor and point into container. turn key on, see if any fuel flows.

--inside tank hose split, pump failed, filter or screen clogged. open tank and diagnose.

--clogged injector. remove injector carefully from fuel distributor (they break easily). point distributor head into container, turn on key. should get very strong stream of fuel. if injector clogged remove and clean, (maybe ship to outside service)

Disconnect the line from the injector and point it at a bucket, turn on key. Trouble shoot it just like an electrical circuit and start at the source/ work your way out from there.

On the 1150 you can slide the air box tubes back off the throttle body and look down to see if you are getting a spray.

Is the exhaust plugged for storage. I used to use an exhaust plug from a motocross bike to keep junk out of the pipe. I always forgot it and the bike would not start with it on.

Tubes slid back.

When one of the hoses in my tank ruptured, I tried that and got a good stream of fuel out of the injector head because with the injector off there isn't any pressure in the line. That's why I now think that starting with the return line is best. If you get a couple liters of fuel in 60 seconds then the pump, filter and internal hoses are all good to go. If you don't get food return flow the failure is most likely inside the tank.

More fuel

Had a similar issue after my 1100 sat for over a year. Empty tank, added a gallon or so - nothing. Added another 2 gallons or so for a total of around 3 gallons, fired right up.
