Onan starts and dies

Thanks for the responses. Carb does not have fuel shut off solenoid. I pumped fuel into container by jumping power to fuel pump. There appears to be a sufficient amount of gas to carb, however I am not a mechanic so sufficient is my opinion. I have a fuel pressure gauge and am looking for the adapter to measure actual pressure.

I am under the impression that the start button overrides safety for starting. I do not know if this applies to my model? I did try holding the start button but gen died anyway.
