07 seadoo gtx doesnt stay running

[Tjk]

Hey guys I have an 07 seadoo gtx 155. Whenever I try to start it it will start, run for a second or two and then shut off. I belive it has to do something with the injectors flooding the engine because whenever it starts and shuts off you have to crank it with the throttle wide open to clear everything out. Then it will start again for a second or two and shut off. I have a parts ski that I swapped out injectors with so I don't belive its that, same with the mpem. Anyone have an Idea on what my issue could be?
Thank you

There is no mpem on a 2007. Do you mean ECU? Did you re-marry the cluster?

Remove the fuel rail and check the spray pattern of the injectors. Usually, it will only be one injector that is flooding.

What you are describing is typical of an ECU failure.

Yeah I meant the ecu. But mystery solved, I didn't have a compression tester on hand so I didn't end up checking it. Checked it today and ended up with 80 80 and 60. Tomorrow I'll tear the engine apart.
