2003 Sea-Doo GTI Le starts. Dies at full throttle

[Rudds67]

Hey guys I know this has been discussed before and I’ve gone through with the usual replacements, new carburetor , spark plugs inspecting the fuel shut off valve clean .
Jetski runs on idle and light throttle .. the moment you try to gas it or anything it dies..
It’s got to be a fuel issue .thesr JetSki’s have fuel pumps? How do I accessed?Spent most of my Fourth of July trying to get the ski going ugh thanks

You'll probably get more help in the right forum. This one is focused on jet boats.

On my boat, having the fuel shut-off left on will cause these symptoms. I have no idea if there is such a thing on your GTI. A clogged fuel filter will also doo it. I'd be tempted to see if you have free flow on the carb side of the fuel filter. It's and easy test and it could help you isolate the problem.
