WILL THAT HELP MY PROBLEM. If so I will be glad to if not SORRY

I have checked all the fuel lines for cracks and found none. I bled the system and got it back to running like it was. I put it back on the tank fuel and it runs the same, besides smokes little more. I guess that from the off road fuel. When a injector pump goes out does it just go or does it pump or work every now and then? Also can you take the injectors out and clean them without buying a kit?

Off road and on road is all the same fuel. That shouldn't made a difference.

You can have the injectors tested at any diesel shop. It shouldn't cost much. I think the last ones I had tested were $4 each.

Thanks for the help DT86. I will take out the injectors and have them tested. If they check out ok i guess i will pul the injector pump and have it tested to. Just strang it will run for a few min. then go dead. It is running kinda rough. After that run it will crank but go dead right away. If you let it sit for a few it will go through the cycle again. ????????? it looks like it would be the pump or injectors.

Are you sure you dont have a restriction in your fuel delivery system? My tractor has a screen up in the tank and the only way to get it out to service is to unscrew the fuel bowl from the tank. If it were me I would put in 5 gallons of diesel and then put a piece of hose on the fuel outlet and into a gallon jug sitting on the ground and time how long it takes to drain all the fuel. It should flow a gallon a minute or so with no gulping or slow down.

I agree that it sound like fuel problem. But, don't rule out an air problem...VERY dirty air filter or collapsing hose from filter to intake. Just a thought. Good luck.

Thanks for all of your help. I replaced the hose to the breather. Filter is not bad. I can go out right now and it will start up but run rough and go dead in about 2 min. Start right back up and run for 30 sec. and keep on starting. After running or warming it up it runs smooth but still the same run time frame. Im shure the injectors could use a cleaning. Want hurt. I will pull them off and have cleaned and tested, while there off inspect closely and may replace the hard fuel lines. Then see what happens after its back together. What yaw think about that? Those injector pumps are big $$$$$$ I hope thats not the problem. Oh ya i took like going to the injector pump ,supply, and it had great pressure.
