2013 bmw gt650 maxi scooter turns over but no start.

[Elmer8403]

The fuel pump turns on,it has spark and the fuel tank is full. I read a thread about a fuel line loosen or fall off and cant find the thread again.With the fuel cap off and when I crank it to start I can see wripples in the fuel tank.I think there is a hose off.Tried removing fuel pump but hard to come out like its stuck.I dont want to break it.Please help.I cleared all fault codes also

I had such a problem, crank was turning and motor not running.
The sound says, no compression and the injectors sounds not good with a stethoscoop
After long starting it runs on 1 cilinder, later 2
Fuel and injectorcleaner in the fueltank (Wyns) and the problem is gone.
Injectors sounds nice and tikking.
Motor runs much better.

Yes yesterday we found the fuel pump was working and we think the injecters are bad or dirty.Also putting new spark plugs in it. What can you clean the injecters with?

I use this every six months, 1 oz. per gallon during fill ups ... two fill ups in a row.

Doesn't seem to be related here but idle actuator hoses have been an issue. Lots of complaints about stalling due to cracked hoses and loss of compression.
