Suzuki df300 - fuel pump?

[mattiasb]

Dear forum,
Just changed oils and sparks on a Suzuki df300. Tested it on land twice afterwards without any problem. Set har back to water and she won't start! I'm out of ideas, however the sound you usually hear upon turnig the ignintion on is not there anymore and there is no petrol in the internal filter. Checked the electrical but it seems to be fine. I suspect the fuel pump but would love some ideas what more to check and if the fuel pump can be repaired or should be changed.
Engine is a 2008 and roughly 450 hrs.

Thanks!

All fuses in the box inside the Engine are ok...
