Oil & Fuel 5225: Changed final fuel filter - engine started, then stopped.

[Creekpaddler]

I changed the final fuel filter two days ago on my 5225. Then I primed the fuel system following the procedure in the maintenance manual: "loosen the bleed screw... ...Push the priming pump until fuel runs out smoothly". Then repeat the process.

The engine started up, then sputtered and died. It will not start up now. I suspect air in the fuel lines. When I pushed the priming pump, I did not feel very much resistance. And I pushed it many times.

I did not have this trouble when I changed the filter last year. There is fuel flowing to the filter, and there are no air bubbles coming from the fuel tank.

What do I need to do to fix this problem?

You may need to crack the injector lines.

Also if the pump is at the high point on the cam it will not pump with the lever. You need to crank the engine and hope it stops at a different point on the pump cam.

I've tried cranking it several times, but no dice. It wants to start - just no fuel. And there is fuel in the line between filter and engine block.

Crack the injector lines at the injectors and crank till you get fuel with no air coming out.

Went to JD parts to see what the injector looks like on a 5225 and the following is what I found #12 (RE530825). Is bleeding this done any differently?

The following is more for future reference, but thought I would include it. It came from a Utah State publications.

When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel into the cylinder.
Here are the steps to take in bleeding air from a diesel fuel system:
1. Turn off fuel valve.
2. Clean outside of filter housing.
3. Install new filter element and new gaskets. A little oil on the gasket will aid a tight seal.
4. I'd suggest that you fill a spin-on filter with clean fuel before installation.
5. Open the bleed plug on the filter closest to the fuel tank.
6. Open fuel supply valve so that the fuel is available to the filter and pump.
7. Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator's manual.) Pump several times until full flow, without air bubbles, escapes from the bleed plug holes.
8. You may need to bleed filters, fuel pump and lines to the injectors.
9. Close bleed plugs after all air is removed from the fuel tank, filters, settlement bulb, and fuel pump (only one at a time working through all bleed screws beginning closest to tank and ending at nozzles if necessary).
10. Try the engine; if it doesn't start or runs poorly, you may have to bleed the injection line.
11. Loosen injection lines at the injectors about one turn. The use of two wrenches will prevent the binding or twisting of the steel lines. Usually, it is enough to bleed just half of the lines at a time.
12. Crank the engine until all air is forced out and fuel is present.
13. Engine will start to pop on one or two cylinders.
14. Tighten the injector lock nut one at a time to tell by sound which cylinders are firing properly.
15. Run the engine until it runs smoothly. This will bleed the other injectors.
No attempt should be made to service the injection pump or nozzles. This requires special tools and know how. All new gaskets, O-rings, and seals will have to be replaced to prevent leaking.

The directions given are quite precise. Just follow them and it will start.

Does anybody have a link to a pdf for the shop manual for the JD 3.0L Powertech 5 cyl diesel turbo engine?

Sometimes when you can't get it bled we have pressurized the fuel tank. don't get crazy, a small amount of air from your compressor is all that is needed when you crack the lines to bleed.

Before we figured out that the fuel gauge quit working in our Ford Tractor we ran it out of fuel, and we dragged it with a pickup to start it. Took a little while, but spinning the engine that fast pushed the air out and it fired up and had no issues with it. Happened twice and we did that both times.

There is always ether.
