[Cubansuperman]

My 2011 Sea Doo challenger 210 with only 19hrs brand new fuel pumps but port side engine is stalling when I give it throttle no engine light on so I'm not able to read any codes yet I had to drive on one engine for 1hr till I made it to the launch please help if someone ran into this issue before

If you are not getting any codes, it is probably something that is not reported to the ECU. Fuel pump is one of those, but you replaced already. Did you change the plugs on it yet, it is a cheap thing to try first. I change mine every season. Injectors (possibly plugged) and ignition coils are other items. Have you checked the supercharger? Battery voltage at least 12.6 volts?
