I have a 180 diesel and it won’t start. I used it this summer on a posthole digger and had no problems. Started and stopped many times. 2 months ago I moved it in the barn. When I went back to start it a couple of weeks later it wouldn’t start. Looks like no fuel is getting to the cylinders since the exhaust is clear when cranking. I have tried the hand primer but it pushes really hard. Definitely fuel to the primer as it leaks a little when pumping. Tractor acts like it would if you tried to start it with injector knob shut off. This is really perplexing me. Any help appreciated.

smell the fuel in the tank, and report back.

Ok. I’ll have to say I was skeptical, but I smelled the fuel tank and it smells like varnish. Used a flashlight, still half full with red diesel, but it doesn’t smell like diesel. I’m guessing this means something.....?

smell of latex paint is what I tell people how to tell when the fuel has gone sour. It gets gummed up, and most likely the pump will be gummed up inside too. Tractor may have been ran a couple of months ago, but how old was the fuel that is in it? It can take a year to use the fuel, and it can sour in much less time than that.

So, I should get the pump rebuilt? Is there something that would be sticking, like shutoff valve? Most of the fuel wasn’t that old. Put new on top of some old probably.

sadly, if the plungers are stuck, then yes, you will need to get the pump properly serviced by a qualified person. If no one around you is capable, pm me and I can help. You will need to clean the tank and lines of all the old gummy residue. It looks like syrup sometimes. E-85 works good as a cleaning solvent for the tank, lines, and filter base. I rebuild the primer assemblies along with the pump and injectors if they need it.
