HELP! 1986? Case 580D Construction King Backhoe.

[MikeM22]

Hello, I recently inherited a 580D Case backhoe from my father. The machine has been sitting for awhile but it ran before it was sat. It had new looking filters on it but I replaced both fuel filters and the air filter anyways. Checked the oil and it looked clean on the dipstick, filter looks newer.
It needed a new ignition switch which i bought and replaced. I also bought a new battery and the fuel filters. The machine starts run for a few seconds, sounds good then dies, and it will do that as many times as you turn the key. I had NO idea what could be keeping it from running and i'm looking for some more knowledgeable guidance. Instead of me just guessing and dumping money. I have tried to spray diesel into the air intake after starting, I saw that was a way to fix airlock. Anyone have any suggestions?

Depending on the fuel and how long it’s been sitting, you could have a “chit load” of algae in the tank..
Syphon out a few gallons from the bottom of the fuel tank and see what it looks like..

Did you clean or replace this filter / #14 ?

REMOVE #46 & start the engine.. betcha 1.00 it stays running..

What does that mean I need to fix? Sorry i'm totally inexperienced at any of this. xD

Should I removed all filters/tank/lines and do a full fuel system purge? If so, is there a "best way" to do that?

Just pull 46 & see if it'll stay running 1st..
Inside that return connector is SUPPOSED TO BE a check ball & spring.. if it gets clogged, the engine will run for a few then shut down.. & keep doing it until the clog is cleared..
IF u have an air compressor, remove the line & loosen the cap on the fuel tank & "back blow" the return line, back to the fuel tank to clean any obstruction in the line..
Clean out the return fitting & reinstall.. IF it keeps happening/shutting off, u have inj. pump troubles..
Google> "flex ring".. & save your pennies & get back to me..

BTW> the inj. pump has a name plate on it.. get the #'s off the 1st line & post them.

BTW that is a 1982 silver anniversary machine, not a bad looking unit from the one pic.

I was giving you something simple to eliminate as a problem..
I knew thepumpguy would show up eventually, he’s likely the #1 guru when it comes to fuel systems/problems on this site, so I’d advise you to listen to EVERYTHING he has to say, and do things in that order..
I’ll stay tuned....

I did not. I will this weekend for sure.

Thank you!

Thank you, it was my Grandfather's. He took amazing care of it. My father got it after he passed and it got neglected a little. Now I inherited it from him.

So I'm out here at my tractor, and you were right. I took off 46 and cleaned it out and it runs. For about a minute now. I ended up taking off #46 about 5 times now and keep cleaning it out everytime and the same thing happens... is there another way to get this gunk out that's more effeicent? Also my pump is different I don't see a #14

It could be that the governor ring is bad and flaking off so you may need to rebuild, pumpguysc and give you more info on that.

Did you drain any fuel out yet ??
Reason I suggested you do that is, years ago my JD410 was doing exactly the same thing as your machine, drove us nuts troubleshooting..
Someone suggested the fuel could be the culprit..... I siphoned about 5 gallons from the tank..
It looked like someone shaved Cher’s head, and stuffed all that hair in my fuel tank..
Cleaned out tank, and new fuel, it’s been running great eversince..

I did remove the old diesel just because I didn't know how old it was. I put new diesel in but I did not clean the tank. I didn't know I would have to.

Also the stuff I keep cleaning out looks like rusty red sand

Is the fresh fuel coming from a storage tank. If so that may be the source of the crap.
Is that stuff hard or soft ?
A heavy dose of fuel conditioner may help. It should be added every time you add fuel to the tank.

U could leave off the connector & run the engine & hope whatever is in there washes out.. {doubtful}
