Help Getting JD 6400 Started In Cold Weather After Sitting for 5 years

[landrand]

You can disconnect the wire to the intake manifold heater and then use ether. You will need to be careful to slowly meter the ether in the air filter cannister.
If you get too much it could ether lock on you. If that happens let it set for 10 minutes and try again.

Is this a two man operation or can I do this myself? I'm a one man operation right now. Can I spray ether into the air cleaner and then jump into the cab and try to start?

The manual says that I just need to let it crank for about 20 seconds after changing the fuel filter and that should bleed the system. I've cranked quite a few times by now. Maybe I need to bleed near the injectors.

It sounds like you have a electric fuel pump in the tank and you should turn the key on for 20 seconds...not crank. The above thread says you have to loosen the bleed screw on the filter housing before "bleeding" for 20 seconds.

Yep, just read that as well. Will give this a try today.

If you don't get fuel flow out of the bleed screw while running the electric fuel pump, then there must be a problem with that pump or inlet. Good luck!

Which the key ON & the supply pump running, loosen the bleeder on the filter..
Once u get fuel there, move over to the injection pump..
It should have a bleed screw on the injection pump by the name plate.(CAV/DELPHI) it’s a double screw.. 7/16 body with a 5/16 bleeder..
Loosen the 5/16 until fuel flows with no air and snug it back up..
NOW.. loosen the lines AT THE INJECTORS.. all of them or as many as u can get to..
Now MAKE SURE you have 12v to the shut off solenoid on the injection pump and crank the engine until fuel squirts out of the loosened lines AT THE INJECTORS..
After a couple rounds on the starter and no fuel is coming out of the loosened fuel lines, your injection pump is gummed up after sitting for 5 years and will need to be removed for service..
Good luck

I loosened the fuel filter bleed screw and turned on the ignition. Didn't see any fuel run out of the bleed screw. I also,

Yesterday, I loosened the bleeder screw on the fuel filter and turned the ignition key on several times for a minute or more. I also tried cranking with the loosened bleeder screw. Didn't see any fuel come out of the bleeder screw. It appears I may have an issue with the fuel pump in the tank or perhaps the fuel line. I put 5 gallons of diesel in the tank and I'm wondering if that is enough fuel to cover the pump's inlet. I need to do some research about this pump that's physically in the tank. Thanks for your help!

Loosen the cap at the fuel tank..
Have a 5 gallon bucket ready.
Take the feed line off the filter head.. got fuel??
If no, check to see if there’s a shut off at the bottom of the tank..(turn it on)
If still no fuel, use some compressed air and back blow the line towards the tank.. u hear bubbles..
Now u should have fuel at that line u took off..
If not, add more fuel..

 

[thepumpguysc]

If u do have fuel at the feed line.. tighten it back up and go to the out side of the filter head.. got fuel there.??
If no, pull the filter down..
Don’t forget to keep cycling the key..
Good luck..
But experience tells me, once u get fuel to the injection pump.. it’s not going to go any further..
I don’t mean to rain on your parade.. Keep going and trace that blockage down..& we’ll cross that pump problem (if there is one) when we get there..

It looks like just the pump is about $66 while the whole pump/sender is about $150.
