On my 6.9 liter diesel I have fuel at the fuel filter, but
not getting to the injectors. The only thing I can see in between is what I think is called an injector pump. I
recently replaced my rear main seal, and one connection
on my transmission didn't seem to work right. The linkage
that connects to the injector pump seemed to not fit right
..it would go on, but wouldn't shift right so I left it off.
Can this have anything to do with my problems with the
injector pump. If I need to replace the injector pump,
where can I get some instructions so I dont mess up.
When I started having trouble with it, I was driving down the road and it just quit. I thought it
might have been the electric fuel pump and replaced it to find out that it is something else.
After putting in the new electric fuel pump it ran for about 15 miles and quit again at about the
same place it quit the first time. My son poured a small amount of diesel into the air intake
and it cranks and runs till thats gone. There is fuel to the fuel filter. I disconnected the line
coming out and have fuel there.
Dave, given the scenario of how the truck just quit while driving down the road, do you think
there is some way for the injector pump to get air in it?
Gknight,
Daves trying to help you.
but it often takes process of elimination to help.
you should consider answering his questions asked,then he can answer yours much more easily.

Dave, No I haven't tried this. If you think there is a way for
air to get into it as I am driving it, after I try bleeding the
pump, where do I look for the air leak culprit. This is the
second time in as many days that this problem has occurred.
The first time, the truck stopped like it ran out of diesel.
We looked it over for a bit and tried cranking it back up and
it did, but ran like it wasn't getting fuel right. I changed the
electric fuel pump and drove it a few miles, got up top 75
mph and it seemed to be ok. The next day I go about 15 miles
in it and it quits and wont start back up for me.
That seems to be the way it goes for me a lot of the time lately. This is my first diesel.
I will try bleeding a couple of injector lines at the pump and see if that does
anything, but wont mess with it tonight. I'll let you know tomorrow how it turns out. Thanks.

I was told that this one did not have a water seperator. It looks like there are some controls
below the dash for this, but was told that all of this had been disconnected.
When was the last time you changed the fuel filter? Does it die while driving or coming to a stop when your foot is off the accelerator?
If its the second thing dying while stopping which has happened to my truck. Run a good dose of diesel clean or atf through the system. My govenor was sticking in my injection pump and the diesel treatment cleared it right up.
bpainting, It wont crank at this time. It has been a while
since I've changed the fuel filter, but fuel does come
through when disconnecting the flexible line that connects
to the top of the filter connection. I doubt that I have two
thousand miles on the filter. I can get another one though.
Where do you put the auto matic transmission fluid in
the system to clean out the injection pump..maybe pour
some in the new filter?
Where do you have your electric fuel pump mounted in the system? Are you bypassing the mechanical pump? The EP should put a possitive pressure on the system so air cannot get in. My bet is the fuel filter like bpainting suggested. Fill it with diesel kleen, turn your EP on for a couple minutes, bleed the air from your filter and you should be in business.
