17.5 Martin yanmar generator HELP
#1

I’m in far west Texas in San Angelo I am looking for a guru I can travel to to help me get this generator rolling. It’s been sitting for years and I have tried to get fuel at the rails but I was unsuccessful. I had help from Gordon on here (he is a saint) but sadly he is way up in Ohio. I am willing to travel around maybe east to as far as Tennessee/Georgia If anyone is really good at fixing these generators pls send you contact 

Also need help with replacing capacitors on all three SCS basements ac

If you need help getting the engine to run you could try contacting a local repair shop.

I know of no one with more knowledge of generators than Gordon so your going to be hard pressed for getting better info here. Please recap on what you have done and found. What is your fuel level in the bus? If it's below 1/4 tank the gen will not have a source of fuel. Have you tried getting a 5 gallon can of diesel and running a fuel line direct from the pickup pump to the can of diesel?

oh he is phenomenal. no I haven’t tried that. I think he mentioned that as well the finger is it’s so hot in Texas that I literally would dedicate maybe 90 minutes and I would be like OK. I’m done for the day lol Gordon mentioned that I should probably put that fuel pump on there, but I just figured it would be easier to just pay someone lol I’m sure I could do it. I just need some air air-conditioning

Jack just reminded me…. On my coach (316) the generator has a seperate fuel tank. If yours is similar I would manually check fuel level . The gauge may not be correct.

So I just recently replaced my fuel pump on my generator. I will tell you that my pump would sound like its running but it was not pumping. Not sure if you have the same style pump but the carter pump mine had an internal magnet coupling and the pump would spin sometimes and then stop spinning with just the slightest amount of force put on the pump. 

Here is my post going over the replacement of the pump:

Now looking closely at your photos trying to find a fuel pump, it appears you have a Makuni fuel pump, not sure what model it is. It seems that the Makuni fuel pumps use vacuum to run them, not sure how they are making this work on this engine or maybe this model of fuel pump is not a vacuum type. Not sure if Gordon had any insight on the fuel pump, but may call Martin to see what the pump part number is.

when I opened the banjo style bolt and hit the little lever I get fuel coming out of the lines. It’s only when I try to open the hard lines that I don’t get fuel at the fuel rail

Where is your fuel tank for the gen? I always thought it just had a line gravity feed to the bottom of the two coach tanks   I would love a photo

The valve you see is to seperate or combine the two tanks as needed.

I’m pointing to the injection pump solenoid. You should see that retract about an inch when you crank the engine. That will allow fuel to the injectors .
