Ford 6600 injector pump

I installed a new rebuilt injector pump. I bled the system and get fuel at all the bleed ports. But get no fuel out of the fuel lines at the injector pump or at the injectors. I've checked the fuel shut off system and the rack moves as it should. So why don't I get fuel into the lines going to the injectors?.
 

You don't say, are you cranking the engine, with the starter, and the fuel set to run while bleeding the injector lines?
 
Open the throttle 1/2 way and push in the retard start button, then crank engine with all injector line nuts loose at injectors. You should then see plenty of fuel at
each injector after air is out. Tighten the nuts and start engine.

Yes we cranked the engine with the starter and the fuel set to run.
but no fuel coming out at injector lines.
 
WE've cranked the engine with the lines disconected at the enjectors and again with the lines disconnected at the pump and still no fuel. I removed the cover from the rack cover to see if the rack was stuck. The rack moves when it's pulled to shut down and back when it's to the run position. The lift pump works great when bleeding the system and when cranking the engine with the bleed port open at the top of the unit.It acts like the fuel shut off is stuck in the off position even with the rack moving as it should.
 

Did you loosen the fuel line going into the pump and work the hand primer to see if you had fuel to the pump

Some using Wix or NAPA filters have mistakenly got the upper seal in the wrong place blocking fuel to the pump
 
I think at this point I'd be contacting the place that sold you the pump and telling them the same thing you've been telling us. From my vantage point, if everything you say is correct, it should be spitting out fuel. Unless the pump is not turning over, like maybe a key was left out of the drive hub? Do you see the plungers going up and down as you crank the engine with the rack cover off?
 
With the lines off at the pump, hold a finger over
one of the outlets and have someone crank the
engine. Dont press down hard, theres enough
power there to inject fuel into your skin. Just let it
lay there lightly, to act like a check valve. If that one
starts pumping, then there is dirt in the delivery
valves, introduced when you put the pump on, and
the rush of fuel during bleeding washed it into the
pump. This is just a guess, as I had a similar
situation with a 3cylinder Deutz after customer
changed the fuel filter , then could not get it started.
Little short fibers stuck in delivery valves, never
could tell where they came from. Had to remove all
3 delivery valves and take them apart before it
would work.
 
Is it possible that I don't have the fuel shut off cable adjusted right? The arm on the pump goes from about the 11 O'clock position to 1:30. With the cover off the rack is all the way to the left when the shut down knob is pulled. Then when pushed in it goes all the way to 1:30. Is this to far? When you pull the knob to shut the fuel off how far should it come out? Is it possible that the rack goes from off thru run and the back to shut off?
 
Jim, is it possible that I don't have the shut down cable adjusted right? The lever or arm on the pump goes from about 11:00 o'clock when pulled out to about 1:30 o'clock. When pulled out the rack is all the way to the left. When pushed in could it go to far to the right and shuts the fuel flow off again. Should I loosen the cable at this point and move the arm back some where midway and thighten the clamp? I guess I could try moving the arm to the left while cranking the engine to see if I get fuel out to the lines.
 
Thank you Fritz, Is it possible that I don't have the shut down cable adjust right? The arm or lever moves from about 11:00 o'clock when pulled out all the way to about 1:30 when pushed in. Is this to far? Should I remove the cover plate over the rack and move the rack all the way to the left with the cable pilled part of the way out. Then tighten the clamp and push the knob in to run to see if I get fuel to come out at the lines when cranking the engine?
 
Sure its possible. But when you have a real head
scratcher like this, is best to disconnect it
completely, and move the lever to its maximum
travel; get the fuel flowing first and worry about
adjusting the stop cable later.
 
Good way to loose a finger or die of blood poisoning. The accepted cure for diesel injection into a finger is to amputate it. I would not ever!!!!! recommend using a body part for testing high pressure fuel or hydraulic systems.
 
So I'd probably pull the side cover off the pump again and look for two things... Rack movement and plunger/cam movement. First
pull the shutoff cable out and see if the rack pulls forward as you pull the cable. THen see if it moves rearward when you push
the cable in. If it does the rack is free and the plungers should be free to move and meter.
Next, crank the engine and see if the cam turns and the plungers move up and down. If they're moving and the throttle is set to
half or more, it should pump fuel. If it doesn't, remove it and send it to a reputable pump shop.
Having done this you will confirm the rack travel and the drive hub security that Bern is talking about. If the pump doesn't
turn over, then go back and look at the drive. But if everything turns and moves as it should I could only suspect issues with
delivery valves or pump plunger phasing and that should be done on a bench by someone competent. And if that's the case, and it
were me.... not for any amount of money would it be the last guy,

Hi Rod, are you certain that when you pull the shut down cable out the rack moves forword and rearward when pushing the cable in? I've had the side cover off andI want to think that when you pulled the cable out the rack moved rearward. The arm or lever on the side of the pump where the cable attaches onto moves to the left when pulled out. Iwant to think this also moves the rack rearward. Ill have to go and check this out. This tractor ran but it wouldn't hold its prime after not running for 2 days. It was determent that the fuel lift pump was faulty so we replaced it and bled the system but now we're not getting any fuel out to the lines going to the injectors. This rack is supposed to allow fuel to flow to the plungers as they move up and down. The fuel lift pump works
when turning the engine over with the starter. Any Ideas?
 
To the best of my recollection, yes, pulling the shutoff cable out to stop will act on a butterfly that pulls the rack forward to
zero displacement. When the shutoff is pushed in, the rack will advance rearward and when throttle is applied it will advance
farther rearward against the maximum fuel stop. You can remove the cap over the rack on the rear of the pump to monitor it's
movement or remove the side plate.
The pump plungers should always be immersed in fuel and metering is achieved by the relative position of the rack and port/helix
of the plungers.

How do I check if a plunger is stuck in the injector pump? Can I view the plungers when I remove the side plate that fits over the rack?
