I have an onsn 5500 marquis gold gas generator. We ran it last month for a week during the day. Got home and it ran for a couple of seconds and won't start. Changed the oil and gas tank is full

Is this gasoline or propane fueled?

Code 37 is a bad set configuration, that means engine cranking speed and generator output aren't happy with each other..

Not normally, the board outputs to the fuel pump, or LP shut off solenoid. It doesn't know the difference.

Try under the bench seats around the table, near the heater.

Does it bog down? if so have engine checked for ability to deliver HP. Cylinder compression, leakdown test. When was it tuned?

Check fuel pump pressure, how long has it sat. What load is on after it stops?

What is the question? You want a free service manual?

I can help if you describe the issue in English please :(

shut fuel off at tank, pull fuel line off carb ,slowly turn on fuel if fuel flows freely(real good stream)your carb needs replacement(cant buy parts to rebuild EPA) if fuel just barely trickles out . there is a screen in the fuel tank that is probably clogged

Hi,
I can give you the "OWNERS MANUAL" for the 5500/8200 Model 16172 Electra generator, but I don't think that is what you're looking for, is it? I purchased the generator at the Navy Exchange and got the 3 year warranty on it. When it suddenly wouldn't start going into it's third year, I contacted the warranty center and they told me where to take the generator for repair. That shop worked on it and finally got it to start, but when they attempted a second start - the starter 'dogs' hung up and were destroyed. The shop attempted to locate parts, technical services, etc., for Electra, but couldn't find anything and the warranty center finally returned my purchase money and the shop sent the generator back to the warranty center. Does the manufacturer still even exist? Don't Know.... Tom.... Pensacola, Fl
