Oil & Fuel Yanmar fuel shut off

[2manyrocks]

Was it running normally at all before this happened or did you just buy this machine and haven't been able to get it to stay running? Was it running at all?

What kind of temperatures are you trying to start it in? If you have cold weather, do your glow plugs work? Is that why you had to use starting fluid or did you have to use starting fluid because you aren't getting diesel to the injectors? Did you try loosening one of the lines to one of the injectors and then cranking the engine to see if fuel is getting to the injector?

Some more info might stir someone's thoughts on your problem.

Danny, the motor is in a older Takeuchi mini excavator...do you know who sells parts for this motor?? I still cant get it to start

I should be able to furnish parts for your engine, I also have the operation manual for the T-(H)LE engines. The manual has Specifications & a Trouble-shooting section.

Well, I removed the muffler today and check all my fuel lines once again..I turn the machine over, and with a little help from starting fluid, It started, But I couldnt keep it going with the throttle,

I wouldn't use starting fluid, you could end up with some busted pistons.

One more question..Is it ok to use a electric fuel pump on a diesel engine?? I dont think my pump is pushing enough fuel. I am kinda new with diesels, I bled the system, and at the fuel injectors, the fuel wasnt coming out that strong.. I dont know how much pressure should be coming out?? The engine is in a Takeuchi TB35S

You won't get much pressure out of the line, the pressure ( 2275 psi ) is what comes out of the injector nozzle.

Well, I am still not getting anywhere with this machine..I had it running for about 10 seconds, and then she died..tried to start it back up, and nothing. It wont start on its own, it will only start with the help of starting fluid, and I know thats a bad habit to get into...I dont know if the injector pump is bad? I was going to try new injectors next..But I dont know if it will be a waste of money..As my wife calls it the money pit.

Why don't you call who bought it from. They may know how to start it?

The machine hasnt been running for about a year prior to me buying it...

Since it has not been running for some time, a through cleaning of the fuel system is the place to start. Drain the tank, change the fuel filter, purge all lines and try to get fresh fuel in everything. I know that you did this after you had it first running, but running with that old potentially contaminated fuel could have move undesirable material through the system.

Rather than change out injectors, you could simply have them tested and cleaned. They could have junk in them, especially if there were any traces of water in the last fuel that passed through the machine.
