Problem with Ford 1999 F250 Regular Cab

1999 Ford F250 7.3 stalled and wont start back up?

I have a 1999 Ford F250 with a two tank golden fuel system installed. It is an older installation in being that the main tank is the veggie tank and a 19 gallon tank is in the bed for diesel. I recently experienced a loss of power and sputtering in the veggie side so I switched back to diesel and ordered the Racor R120 filter and replaced it. Shortly after I switched back over to veggie the engine completely lost power and stalled. I haven't been able to get it to fire up since. I was told that it is probably hydro locked but I am not sure what that means. I am guessing I probably got some air in the fuel lines but am not sure how to properly bleed them now that it?s too late to prime the filter properly. When the engine does turn over lots of white smoke comes out of the exhaust, a symptom of air in the fuel lines, but I have drained the batteries four times trying to get it all out. What is the proper way to get all the air out and also to push all the veggie oil through so that I can start it off diesel since it stalled on veggie oil?

Ok here is the meaning of firing order The numbers 1-5-4-2-6-3-7-8 represent the order of wish cylinder the distributor send a spark as it rotates Starting whit cylinder number 1 The distributor will have to rotor on the number 1 cylinder spark plug and the piston on the number 1 cylinder will be at the top So the fuel and air will be compressed and ignited by the spark plug. The next one will be the cylinder number 5 to do the same as the crankshaft and distributor rotate Next will be number 4 then 2 then 6 ? 7 ? 8. You get the idea "10 Degrees" The degrees represent of spark advance You may think gas explode instantly but it actually take a little time So for the explosion has maximum power when the piston reaches the top of the cylinder the distributor send the spark a little ahead of time 10 degrees of revolution is the recommended by the manufacture but that can be adjust buy losing up the distributor clap bolt and manually turn it. In order to adjust that you need a timing gun Than will flash light on the crankshaft pulley (harmonic balancer) and you will see a notch and a series of numbers than represents the timing advance Note If you have not turn the distributor by loosing to button clap bolt I recommend to live it alone and go to you local part store and get the repair manual find the firing order to see wish wire go to wish cylinder Rotate the crack shaft pulley on till the notch is on 0 and see if the distributor rotor is tours cylinder number one. Cars than don?t used distributor do that automatically and constantly adjust the ignition timing by the computer.

    • no no

      Top dead center is the moment piston at cylinder number one is at the top almost touching the cylinder head and the crankshaft is on the cero mark.

      the top of the distributor cap the one of the middle is the plug than comes from the ignition coil

      The ignition coil is what gives the spark to the distributor and the rotor position will give the spark to each individual spark plug one at the time.

      It seams to me you got all cables cross over.

    • Use a spare spark plug disconnect one of the spark plug cables and plug it up to the loose spark plug and hold it ageist the engine while some one crank it up for you if you don't have spark then you have some other electrical problem if you do have spark

      Buy a ignition timing gun and careful read all the instructions that will teach you how properly adjust your engine timing and you see if you have rem the cables wrong
      timing gun is a strobe light than makes the illusion than the crankshaft pulley stop moving while your engine is rotating

      make sure to use the timing gun clamp on the number one cable.

      dont buy the spensive gun whit a timig ajusting knob or digital ajustment that will youst confuse you more just buy a sheap one whit just a triger nothing more.

are you losing coolant? ford had a huge problem with that engine,and the coolant eats the main bearings.
the defect is in the EGR valve setup.
check with ford,they are aware of the issue,there are thousands of them

    • it might be able to be fixed but you would have to tow it to a shop and have them check the head to make sure it didnt messup the valves or pushrods or warp the head
