FORD 7000 WON'T START!

Ford 7000 tractor will not start!

Yesterday it ran fine. This morning I started tractor, plowed snow for about 15 minutes. Temperature was about 14 degrees. The tractor quit running and acted like it had a frozen fuel line. Tried to restart the tractor. It would act as if it wanted to start, but it would not. Checked all fuel lines--all are clear. Continued to try to restart the tractor. A couple of times it ran for about 30 seconds, and then quit. The tractor acts as if wants to start, but it will not start. I put heat in the fuel, but no result. Have been trying to figure it out all day. Help! Thanks.

Maybe a dumb question, but I assume you have fuel flowing through the lines? I get from what you said they're clear - no obstructions, but this happened to me several years ago w/my 8000 in similar conditions and the fuel had gelled. A little would run through the line, but the fuel in the tank was gelling pretty good, so flow was intermittent. I used Howes to free everything up and it ran fine. Good thing about a diesel is if you've got fuel, air, and compression, not much else can go wrong. Good luck.

Thanks for your response. Yes, all the lines are clear and I am getting fuel all the way to the injector pump. Still can't get it to start.

When was the inj pump oil changed?

sotxbill · Mar 4, 2012

fuel is jelling at filter and starving fuel flow.

I wondered about that too, but I went to town and bought a new filter. No success. I am thinking it might be the fuel lift pump?

Changed the oil last summer. Don't think it is that. I did notice that the lever on the lift pump is soft instead of firm. Guess I should order a new one. Any other ideas?

At 14°F, you most likely have a water in your fuel and it"s frozen on the filter restricting the fuel supply. If you have summer diesel in it, then you may have jelled fuel. In either case pull the filter and see if it"s clogged with ice or waxy fuel. Replace the filter, treat the fuel in the tank with the appropriate additive and then bleed the syatem starting from the filter through the injection pump and then to the injectors. Make sure your battery is fully charged because you may have to crank for a while to bleed the system.

One of my tractors would run but not at any RPMs for any length of time. I had fuel getting through the filters and the injectors. But the question is not do you have fuel getting through, but HOW MUCH FUEL? WILL THE FUEL RUN STRONGLY FOR 30 SECONDS? just because some fuel comes out does not mean that it is not plugged. In my situation it was blocked where the return line tees in. It would drip about one drop per second.

I checked the fuel line from the tank to the bottom of the lift pump. Got a full stream of fuel. I am wondering if I need a new lift pump. When I work the lift pump lever, it goes up and down real easy. Shouldn't the lift pump lever be firm against pressure? What do you think?

The lift pump costs only about $35.00 so it would be short money to eliminate a possible problem.

Parks · Mar 5, 2012

I decided I had better remove the fuel pump and inspect it. What I found was a piece of metal broken off inside. Ordered Ford Tractor Fuel Lift Pump D8NN9350AB to replace it. Case closed. Thank you to everybody who responded and helped!
