I am not an expert in jet skies but just a thought. Did you check that your fuel pump works good? Test the pump for quantity per 10sec according to the service manual. It may just gone bad. Good luck and hope I've helped.

I have a starting problem with my 2005 Yamaha XTL 1200 jetski it turns over but won’t start I took out the spark plugs and cleaned them they were black but still wouldn’t go

Black plugs indicate carbon build up. Try starting with ether sprayed into carburetor. If it fires, clean fuel system with spray and additive. Use the fuel engine was designed for.

1999 Yamaha GP760 Jetski, replaced battery but need code to start and we don't know the code, where would we find one and how do we enter it?

Behind front storage container is a wiring harness, locate the single blue connector and disconnect, red light should be on dash now hold mode button down until it says SET. enter new code then reattach connector.
