Oil & Fuel TC 29 no start

[White74horse]

I have a TC29 , turns over , is getting fuel , puffing smoke as it tries to start but will not start at all , any ideas or thing I should check?
Has fresh fuel and filter.

Have you tested the glow plugs?

Air in the fuel lines, low compression, bad glow plugs, bad fuel, clogged air filter. Lots of things it could be, can you be more specific in what you have tried? I would start with bleeding the fuel lines again if you repaired/replaced anything to do with the fuel system. You never said why the tractor just "didn't start".

Fuel lines are bled , seems to be getting plenty of fuel , turns over fine ,air filter is good , have not had a compression check done.
Ran good , sat for 7-8 months , will not start,
new starter and ignition switch.
Glow plugs working.

Puffing smoke suggests the fuel system is working.
Been sitting for 7-8 months so battery may be weak now? Engine needs to spin at speed to develop the compression to start.

Use jumper leads from your car/truck (engine running above slow-idle) to boost your battery.
Also check battery connections and earth to chassis.

I would agree that puffing smoke suggests you are getting fuel, but possibly air as well. Yes, you may have a weak battery and not enough speed to create enough compression/fuel mix for atomization. Why did you replace the starter and ignition switch? Is that why it sat for so long? Have you bled the fuel lines at the injectors? If not crack each line while it turns over and with the throttle set to full speed, once you see no more air bubbles tighten them up, also do them one at a time. If all is good there I would perform a compression test, very simple to do since it's tested through the glow plug ports.
