F250 6.0 diesel, cranks but only runs for 1 sec

Cranks but only runs for 1 sec, have replaced fuel filters

    Update with more detail: Problem started 3 days ago. Cranked the truck and engine ran for 1 sec and died. After many more attempts it finally ran but extremly rough. Lots of black smoke. After 30 sec it leveled out and was fine the rest of the day - starting and running. The next day in the AM same problem only now it will not run. First step was to replace the fuel filter, oil is full, air filter was replaced 2 months ago, no restrictions. No codes in the computer. When I turn the key, glow plug dash light stays on 5 to 10 sec as normal and I hear a click from the CPCM. I verified B+ voltage at both CPCM connectors and 12v on red wire when the key is on. I then disconnected the connectors at the glow plug rail on each side and using a dvm with one lead connected to the block, ohm'd out the gow plugs and all are less than 1 ohm. I then set my dvm to read dc voltage and with the key off, I read 10.29v on all 8 leads that come from the GPCM. With the key on, still reading 10.29v. This does not make sense. I would think that I should read 0v with the key off and 12v with the key on (for the first 2 min). Any suggestions or am I looking in the wrong area?

SOURCE: 2000 ford f250 super duty 4x4 7.3L diesel oil leak

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.

SOURCE: 1999 ford f250 7.3 diesel, leaking fuel out of the drain tube from the fuel filter

The drain valve is attached to the fuel filter with 4 screws with the star head. You can use a correct size van allen wrench to unscrew these screws (which is hard to do with little space) and put your new drain valve in. The new drain valves have huge O rings that work better than the seemingly non existent washers that come from the factory. You will first need to take out your fuel filters and drain the filter body because when you take the water drain valve off, all the diesel will come out any way. This is a good time to take apart your whole fuel filter and clean it out good. An air compressor works great. Be careful with the plug in fuel heating element if you do take the plate off that it just under the filter (two allen screws). You can unplug it and clean the bottom of your filter housing so your water drain does not plug up with the stuff on the bottom of the filter housing.

SOURCE: my2005 f250 6.0 l diesel will crank but not start and run

Possibly a crank sensor on or around the harmonic balancer, acts as a magnet like on an old buick. When you get the truck to fire up run it until she gets hot shut it and try to restart if no start continues try spraying starter fluid on the crank sensor itself. What happens is the sensor overheats and wont register that your cranking the engine. Spraying the starting fluid on the sensor will cool it dramaticlly enough for you to restart.

SOURCE: 04 f250 diesel cranks but won't start

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.

SOURCE: 2004 Dodge ram diesel just die out of the blue.

Michael- I just had the same think happen to my 2004 Dodge just yesterday. The dealership tells me it's the transfer pump, but it now requires it to be moved from the side of the engine to the fuel tank. The parts seem to be scarce, and may take a little over a week for me to get them here in Boston, and the total job is $1100. Hope you got your's fixed.

Replaced leaking fuel filter, primed filter and now will not start.


IT will never go unless you bled the air out of the system. Find all the bleed screws and pump fuel out until you get solid fuel. Crack the injector line nuts and crank over until there is fuel drops appearing at each nut . retighten the nuts and then there is every possibility that the engine will start
AS an off side ---Diesels are compression ignition engines and that means that they compress the air to white hot and the fuel is then introduced into this air and ignites IF you spray anything into the air intake then this will ignite prematurely and blow the pistons back out of the sump.
Check that the electric stop solenoid is operational and diesels have to have a fast cranking speed so half flat batteries are a waste of time

Ran out of diesel 1.9 TDi 74kw. have refuelled and cranked engine for 15mins and still it won't start. there is fuel from tank to filter, to pump and return flow.


This is very important for Audi 1.9 TDI engine: IT IS FORBIDDEN TO RUN WITHOUT DIESEL FUEL IN RESERVOIR !!!
This type of engine is equipped with pump-nozzle injectors which develop up to 2050 bar injection pressure !
Remove the fuel filter, fill up with diesel fuel and put in place. After that try to start the engine with accelerator pedal to the floor. Heed of electric starter motor temperature and battery status! After 40 - 50 sec. of start attempting wait for 1 - 2 minutes for battery and electric starter motor revival. After few starting attemptions the engine must start.

Replace fuel pump on 03 Ford F350 diesel


simple : obtain replacement pump from parts provider (no used stuff)

Now help me out here: thats the year they were bolted to the pass side front of engine
and not inside the tank right? (better go look to see for sure)

using a tube wrench unscrew the fuel lines (i use large wire nuts to temp block off fuel leakage)

with a 12 mm wrench undo the two side bolts holding the pump to block

wiggle pump it should come straight off

clean mounting place on block with solvent let dry

silicone back (or use gasket that comes with pump ) of pump

apply pump to block (depending on where crank stopped you may have some tension on arm you will have to overcome to get flange to meet block )

use locktite (blue)or simmiliar thread lock on bolts retighten firmly but not hang up the dog tight

use light grease or vasolene on tube connections don't try to tighten dry

Now the fun part your diesel now has air in the fuel system

there are two ways to remove this ( hard and harder)
your choice here are both methods

loosten the fuel supply line for #8 injector ( I did not say remove) 1 full turn ought to be enough

crank engine 30 seconds only
wait 5 minutes for starter to cool down
crank engine 30 sec again
did it start but runs rough while it's still running tighten #8 injector (caution fuel under high pressure)
engine smooth out good your lucky
engine did not start yet
wait 5 minutes
crank engine 30 sec again
start yet
if so tighten #8 injector up

Now here's something I've done to my diesel to make this much less a hasstle

trace fuel line as it comes up from pump
obtain a small low pressure electric fuel pump and a two short pieces of fuel line
and a few clamps

use tube cutter and cut fuel line just before it bends to go in filter
deburr edges
slide tube and clamps over pipe (both sides)
insert pump observe flow arrrow towards filter

the wires of pump can be stretched over to #1 battery terminals

now any time you change a filter or open your fuel system for any reason
all you need do is connect pump to battery
open sharader valve on top of filter for a few min
and start truck as normal
then disconnect wires and stow away for another day

2004 Dodge ram diesel just die out of the blue.


It sounds like it could be the transfer pump. Turn the key on and then crank the engine for about 1 second but leave the key in the run position and listen for the transfer pump to run. It should run for about 15 seconds after you stop cranking. If not, then you will need to replace the transfer pump with a in-the-tank conversion kit if your is mounted on the side of the engine block below the fuel filter housing. If you already have the in-the-tank pump then it might be siezed or the "sock" might be plugged up with alge or other contaminants. I usually lift the bed rather than removing the tank to replace the fuel module. If the check engine light is on you might want to have it scanned for codes to make sure since the modules can be spendy.

Truck wont start after draining fuel filter?


You may have gotten air in the fuel lines. Diesels cant deal with this as well as gas engines should be a purge / bleeder valve on the fuel lines to eliminate the air. may cough and sputter for a while

Most common cause is a air leak into the fuel system at the filter bleed valve.
