Help!! 6.9 Diesel

I have this 1984 F-350 dually, it runs pretty good, but now I cannot get it to start.
I have recently replaced the glow plugs, the low pressure fuel pump, the fuel filter, and ran a test of the glow plug timer and its working good.

Im thinking that the injection pump has gone out (I hope not). But I can crank it and crank it, but it just wont start. I spray it with starting fluid, and it'll run on that for a few seconds then it dies again.

The injection pump is the only logical problem I can think of...the injectors just are'nt getting enough fuel pressure. I have heard that these injection pumps (mechanically driven off the cam gear) are troublesome and they fail quite often...is this true??

Im not a diesel mechanic, so Im outside of my specialty here!!

Thoughts/Suggestions??

I'm no mechanic either but my father worked with some industrial diesels in his time and he mentioned checking to see if the coupling (if one exists) driving the fuel pump is broken.

Might be worth checking out

Go to the other 460 forum http://www.429-460.com/forum.htm and and post this. richter69 will be able to help you. I don't think he usees this forum.

I think the same thing happen to my friends truck. He changed the glow plugs and stuff. Found out he was out of diesel. :D

First thing to check, Do you have fuel in the filter? If not Fill it with fuel or your favorite diesel additive, Have someone roll it over while you push the schrader valve on the filter head, You will get some air and then fuel. Then crack open at least 2 injector lines 5/8" open end. Do not take them off just loosen them. Crank the engine untill you see fuel at the injectors,. should take about 2 cycles of 30 seconds cranking 2 minute cool down for the starter, retighten the injector lines, hold throttle all the way down and start the truck. If you are below 1/4 tank of fuel I would put 5 gallons in before trying this. These vintage trucks have a problem of the pick up line breaking off in the tank and when below 1/4 tank you will run out of fuel. You mentioned a new fuel pump and glow plugs. Be cautious replacing the fuel pump as they can easily be installed with the arm above the ecentric and not below , they will run like this but not for long before the arm brakes off and ends up in the oil pan. If the injector caps were disturbed when replacing the glow plugs they will leak and allow all the fuel to return to the tank while the truck is parked for a few days.
I would not be to concerned about the injection pump as it would have let you know if it was on it's way out.

Be sure to stop in at www.oilburners.net for a wealth of info on these beloved IDI's. Tell them IDIeselman sent ya.

I'm still here lol.

Good advice above, crack the injector lines at the injector to see if your getting fuel there while cranking, if not and the lift pump is builing pressure there lies trouble in the pump. Verify your getting 12v with the key in the run positon to the pump to "turn it on" so to speak.

I'm more of a powerstroke guy, but these old ones are real simple.

What you'll get with a failing IP is the truck wont start hot, but still will cold.
What you have sounds like your pump is unplugged..(12V) OR.. you got no fuel to the IP. If thats the case you'll have to crack line on the pump, then on each injector till you got fuel there. You also do have a lift pump on the front passenger (iirc) side of the timing cover (looks like an old mechanical fuel pump) that could be causing you issues.

Yes, I replaced the lift pump (its installed correctly), and its pumping fuel up to the IP. I've had my Dad crank the motor over and I opened the shrader valve to let any air escape.

Did the same on the injector lines, one at a time.

Just like Diggindeeper said, sometimes, the truc will start when its cold, but it wont start when its warm.

But even now, it dont want to start no matter what the temp is.

I got a spare IP you could have but i'm an awful long way from SoCal

You got a turbo?

Yes, its turbo'd. I have a friend who has some of these trucks that are wrecked, and otherwise have good running motors. I'll see if I can raid one of the IP pumps from one of them.
But is there any way to rig up a fixture and test the pump before installing it??

yeah i'm sure theres a diesel shop that can test it for you in the area.
you'll have to turn it up a few flats though if its off a nonturbo.

Theres lots of other things that take the same pump too.. 6.2 diesels, i know some small 4cyl john deere tractors have them to.. they just plug every other line.

edit: if you've never taken one off b4 dont just jump into it and unbolt everything. they'res a fast and easy way to get it off.

I don't knwo what other applications might swap, the GM diesels won't, as they spin the pump in the opposite direction.
As for actually removing the pump, DO NOT remove the aluminum cover and the pump gear with the pump, if you do, you will have to re-time the whole engine.
This is a pretty decent article:
http://oilburners.net/brian/idi/FuelInjectionServicing.htm

The pump comes out with all the injection lines attached, you pull the cover on the front of the gear cover(oil fill on most 6.9's) there's 3 5/16 12 point bolts holding the pump drive to the back side of the gear. Then you remove the 3 nuts on the studs(can be a major PITA, stubbys are required at a minimum, some custom bending maybe too) on the back side of the gear housing, slide the pump back and out.

Also when trying to start use gasoline on rag to help not starting fluid!
