2018 GS22 Throwing Error Code

[Jackhaus12]

Our 2018 Nautique GS22 will crank but won’t start. It’s throwing an error code, SPN 1348 FMI 4. We contacted the dealer and checked the fuses. We were cruising around 23 mph and all of a sudden it died. We also went and bought 2 new battery’s but is still doing the same thing.

it originally threw an error code DTC 261 for injectors 1-8 but that went away and now only shows error code SPN 1348 FMI 4.

thanks

Here’s what it’s showing

From the PCM Diagnostic Service Manual...

The ECM has auxiliary low-side drivers that can turn on warning devices or ground electromagnetic relay
coils to control power to devices connected to the engine.
This fault sets if the output for the fuel pump relay is detected as being shorted to ground. If this fault is
active and the high-side of the fuel pump relay is supplied, the fuel pump will run until the relay or high-side
power is removed.

That’s exactly what it ended up being. Relays looked to be in good conditions, however we ended up replacing them and was a easy and quick fix.

Thanks
