Oil & Fuel MX5000DT Fuel Trouble

[phonejack]

Hello,

I have a 2004 MX5000DT. Having trouble when starting. While warming up, it starts smoking likes the dickens, then stalls. It's like the choke is sticking closed. I have been able to get it started at other times when this has happened and then it runs fine, but now it won't start. As I crank it over, it just smokes. I don't think it's gonna start this time.

Any suggestions on what's wrong?


Thank you,

John, in the Adirondacks Mountains, NY

:welcome:
Are glow plugs cycling when attempting to start engine? How long since you changed fuel filter? Is water separator bowl full of fuel or does it have water in it?

This is the 4th time this has happened. Once in summer of 2013, once in summer 2014, now twice this summer. I tried to start it 2 times today. First time this morning, kept firing and chugging smoke, but no go. Tried again this afternoon, just smoked, wasn't not firing. Won't start.

Tractor has been sitting for month now. It happened a month ago to. No problems starting in winter time.

Fresh fuel is in it.

Inner and outer air filters are new. No obstruction.

235 hours on machine.

Use glow plugs on start ups.

I haven't changed the fuel filter. (just looked at it with a flashlight and checked manual for hours to replace--says 100 hours--ut-oh) Gotta change the filter tomorrow. But it acts like its getting to much fuel.

This has been a great tractor. Injectors?? Glow plug cycling, Don't understand that.

Thank you

Only way for your tractors engine to get too much fuel is from a faulty injector which with only 235 hrs is doubtful. Are you quite positive that glow plugs are getting voltage?? I presume you hear fuel control solenoid clicking?? You could consider tow starting it. IMHO changing fuel filter ever 100 hrs is a parts sale ploy!!!!!!! If one strives to keep fuel & fuel containers clean changing filter at 100 hrs isn't necessary

I'm betting the glow plugs aren't working properly...

Probably not the plugs themselves, but they aren't getting power to them every time needed. When they get power, they work and your tractor starts, when they don't, then it chuff smoke and won't start...

Well the fuel filter was really dirty, with water. I drained the petcock a little to get the water out of the tank. Got it started and it runs fine. I'm sure this was the problem. If not, I'll let you know.

Thank you very much for helping
