I just bought a used Haulmark trailer that has a RV QG 7000 generator. It will only run for 15-20 minutes. After it cools down it will do the same thing. It flashes a 33 code. I checked and found that the fuel pump is NOT running and that even when cranking and/or priming, there is no power getting to the pump. Am I correct in thinking that the power for the pump comes through the control board?
Thanks for any info. Dan |

Yes you are correct and it's a common problem.
PC board/control output for the fuel pump and carb solenoid are the same circuit.... After the board gets warm that circuit fails. Replace the control .....probably an Onan #300-5047
