Ford 3910 will not start

[hlbodie]

I bought a Ford 3910 a couple months ago and did not run it during the winter. It will not start but battery is good and turns over good. Fuel is OK out of the filter. I have heard that they can lose their prime. How do I fix that?

There is a small screw that comes out on the side of the injector pump, take it out and pull your fuel stop out and crank the tractor till you see a steady stream of fuel shooting out. While still cranking put the screw back in. After that the tractor should start, though t might be quite a pain to do. Even with bleeding the pump it will still have air in the injector lines )possibly) and you either have to bleed the injectors or keep cranking. I have kept cranking and eventually it will fire, ether helps aids this but i don't like using ether on mine.

I have a 3230, and I believe yours has a similar 3cyl diesel. Bleeding the fuel, from the manual - There's a bleed screw above the fuel filter. Open it until you get fuel, then tighten it. There's a bleed screw on the fuel injection pump (below and foward of fuel filter). Open it. With stop control knob engaged, turn over engine until fuel comes from bleed hole, then tighten. The manual also says something about a rubber primer just forward of the fuel filter that needs to be pressed until resistance is felt, but mine does not have this primer.

Should start up now (after disengaging the stop control knob), unless the problem is something else.

You'll need to bleed the system from the tank to the injectors. Make sure that your battery is well charged. Tighten all the fuel line fittings so they don't leak or suck air.

make sure the fuel cutoff is open. Open up the bleed screw at the the filter and open the tank valve. When soilid fuel ( no air bubbles) comes out of the bleed screw, close it. If there is a bleed screw on your injector pump open that and bleed the pump. Next crack (loosen them but do not remove them. You just want them to leak) the fittings on the injectors starting with #3, open the throttle about half way and crank the engine til you have fuel and no air coming out of the fitting. I do this one injector at a time, other folks loosen all three. Your choice. By the time you bleed the second injector, the engine will usually start and run.
