  • Service engine 3-2 code but engine runs perfect

    I have a pair of 2008 Suzuki DF300 that I just replaced HP fuel filter, regular fuel filter, spark plugs, both thermostats and changed the fluids. Changing those fuel filters required draining the fuel out of them. I primed them back up the best of my ability. Upon starting the engines and got a service engine 3-2 but the engines seemed to be running fine. I hit exit and ran the motors for all day with no issues. Shut the motors offshore hours later and got the same message again offshore. I was thinking maybe the pressure in the fuel lines wasn't enough so I primed the bulbs. 40 miles later at the dock I shut the motors off and back on and the code didn't pop up again. Not sure if it ever come back. I have never seen this code before ever. It just seems weird it happened right after a service. Maybe coincidence but I cannot seem to find a clear answer what this 3-2 code is. Would a poorly pressurized fuel line throw this code?

    Here is a link to the service codes.

    When an issue resolves, the service code will disappear.
