I would suggest first checking the seal on the air box and all connections to your intake. Make sure there are no penetrations where air could leak. As you probably know, the 6.0 has a world of problems, but I cannot tell you if this is related to the engine or not.

SOURCE: Ford F250 turbo diesel cut out and died as left

if you have the 6.0 then the filters are located on top on the motor right beside your oil filter and under the drivers side on the fuel pump, check to see if you have diesel in your bowl where the fuel filter is, no diesel in there your fuel pump might be dead, check fuses to fuel pump and check relay on the passengers side kicker panel, check your owners manual

SOURCE: water in fuel system of a Ford F250 diesel engine.

there is an additive at most auto parts stores and even some gas stations, i forget the name but if you read the bottle it will say something about removing water from the fuel system, they are generally located next to the "octane booster" or "fuel system cleaners"

How to take off a fuel pressure regulator on a 2000 ford excursion


bleed off pressure by disconnecting wiring from inertia switch or pull fuse for the pump, start engine till it stalls. pressure will be zero.
pressure regulator is on fuel rail. They seldom go. If you are losing pressure overnight or low pressure ( below 40 psi), it is likely the check valve in the fuel pump in the tank.

How would I replace my fuel Filter


The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.
  1. Disconnect the battery ground cable.
  2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
  3. Remove the fuel tank assembly.
  4. Clean the area around the fuel filter/regulator.

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

  1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
  2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
  3. Remove and discard the mounting gasket below the filter/regulator.
  4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

To install:

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

  1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
  2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
  3. Apply a small amount of clean engine oil to the O-rings.
  4. Install a new gasket on top of the fuel pump module.
  5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
  6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
  7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
  8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
  9. Install the fuel tank assembly.
  10. Connect the negative battery cable.

Why wont my 2000 ford f250 diesel 7.3 start when it is cold?


Because it is a diesel engine. They use compression to push the air and fuel mixture together. It pushes them together under such high pressure that they heat up enough to spontaneously ignite. If the block is cold, the mixture won't get hot enough to ignite. If you don't have a block heater, you need to have one installed so that it'll start when cold. Your only other hope of getting it started, besides building a garage to keep it in, is to put a tarp over the hood and run a propane or kerosene heater under the engine until it is warm enough to start.

1998 ford 250 diesel, changed fuel filter and now the truck coughs and chokes like gas is not getting to engine. Does it need to have the gas line bled? If so how?


did you prime the new filter (filling it with diesel) before installing if so youll have to check the pressure regulator on the fuel pump but im leaning toward the filter being reprimed.

The HPOP (high pressure oil pump) is right under the filter housing. There are 2 lines that distribute the oil to the cylinder heads. The o-rings on those fittings go out. Kit is available from Ford or International. You will need a special wrench to get to the fittings though.
