Need help. 6.9 not firing.

[Cruiseomatic]

On mine? No, Theres two. Thats what I jack with on the ground in the middle video. Putting power to the fuel pump and IP from the second. Its just to the right of the fuel can.

Try starting off of a battery charger/starter or jumper cables to a running vehicle for a little extra juice.

If it works. At least youll know it something electrical. Ive found jump starting can sometimes get passed weak wires or connections. Also weak batteries and starter.

Are your batteries secured? Loose battery tie downs results in loose connections or kinked cables. Check that both batteries are indeed wired together. I once drove for a couple days with the second battery unhooked by accident. Slow cranks, but it still started and drove.

Heres what im working with.
It has:
2 trucks jumping it off.
2 fully charged batteries in the truck.
2 fully charged batteries off to the side wired in.
And my battery charger set to 200 amps.
So all in all. 6200 amps.
I have some white smoke coming out the tail pipe. And i believe its turning over fast enough. I may be wrong.
But it will not run. Not even on ether.

Exactly how mine sounded when I was getting 0 fuel. Ether would make that weak cough and a little white smoke but no dice until I primed the system and buttoned up some air intrusion issues. I had to fill my fuel filter screw it back on and then take the hard line from lift pump to fuel filter and fill it with a squirt bottle with diesel until it sat flush with fuel on the top. Cranked it over for 15 seconds and fired up. Before I did all of this all of the ether in the world wouldn't actually make it run a bit.

Since it isn't hitting on ether, I would say you actually aren't getting fuel at at.

yep .. if it's turning .. and still not firing on ether .. it's not getting fuel ..

if i run out of gas .. it won't start until i purge the air out of the fuel filter base ..

it will turn and i can use ether .. but i will just go a bit faster .. until it gets fuel also ..

unlike a gas engine .. that can pretty much start on ether and poorly run if you whif it in just right ..

you have a fuel delivery problem .. probably bad IP

Sounds like one cylinder is firing and the engine is NOT cranking fast with the amount of amps you say your feeding it. How old is the starter and how long do you crank before you allow the starter a 2 minute rest to cool down. Are you getting fuel squirting out the filter bleeder.

 

[Terryraulerson]

Yes fuel is coming out of the bleeder.
The starter is only maybe a month old.
I see a bunch of little air bubbles in the return lines. I just cant figure out where the air is gettin in at.
I took all the lines off the IP to see if it was pushing fuel. It is pushing fuel.
Im guessing i have a pretty serious air intrusion problem.
When i crack the two injectors up front on drivers side it doesnt even hit.
I tighten them down and it hits again. Ive tried doing that tonthe other injectors with no results

So say you try to start it 4-5 times like you have been, if you unscrew the fuel filter off after doing this is it still full? Depending on where your leaking at, and not knowing how well some other things on your engine are operating for easy starts it might not hurt to make sure that after you crank it for a while your not draining back to the tank for example.

Just trying to rule out some of the easy things before you move on to the next stuff. My return lines leaked so bad on mine for air that if I parked it nose up when I first got it, all of my fuel from the IP and fuel filter and lift pump would drain back towards the tank and it just wouldn't run until I manually filled everything back up via squirt bottle. Plugging in the block heater for two hours made the oil warm enough that it would spin faster and help itself sometimes to re prime but not always. Eventually it was time for new return lines and olives and no issues since.

Sounds like its got a cylinder or two with no compression, the rhythmic speeding up then slowing down while cranking coupled with the hissing sounds a lot like compression going somewhere its not supposed to. I could just be hearing things, but it doesnt sound right to me. Try Cranking it over with the fuel solenoid disconnected and if it still changes speed that much do a compression check to see which one(s) are fubared.

Edit: Forgot to say that if it cranks over smooth with the fss disconnected then it might just be the way it sounds in the video.

Does that 86 still have the water separator hooked up?
Been thru that a couple of times until I took that out first.
