Bobcat S300 starts but won't run. Fuel all the way to the injectors and has already been bled, lots of smoke when starting and sounds like it wants to run but won't.

That black smoke is because it isn't getting any air to mix with the fuel your putting in it. Your air cleaner is either plugged up completely or there is a emergency shut of flap on the intake that needs opened.
if the bobcat starts and then runs for a short time then dies the first place to look is the fuel system.fuel filters are the most common problems that i see replace those first.i have also found some junk inside the pickup tube inside the tank.there is probably a ball type hand pump to prime the fuel system.give that a squeeze and see if its hard.if thats the case there shoud be a small screw on top of the fuel filter.loosen that screw and see if fuel comes out when you sqeeze the ball.if your changing fuel filters this is also where you blead air from the system,keep pumping untill there is only fuel and no air.if you still get air after pumping for a long time then your sucking air into the system between the tank and pump.after you get fuel there close the screw,loosen the injector lines going to the injectors,crank the engine,and tighten when fuel comes out (keep clear because that is high pressure fuel).after you get fuel at all injectors and they are all tightened it should start.
Hi
White smoke is usually a good sign of un-burnt diesel so reading your post and all the things you have already changed ie the glow plugs I would have the injectors tested to make sure they are atomising properly as it sounds to me like when your car isn't under load ie at low revs you have a cylinder that isn't firing correctly
Hope this helps Nick
Check for compression on your cylinders. That would tell you if you have a bad head gasket or a bad head.check your distributer and see if is good, i seen that happend too
Could be engine speed sensor. All fuses need to be checked. Any smoke when cranking? Any fault codes? A bad fuel solenoid could cause no start if fuel is good.
I'd get your injectors rebuilt, and tune up your injector pump. Run a little seafoam in the diesel tank, and in the oil. Should make it clear right up.
jlwhelen,
I will suggest that perhaps the blue smoke is not purely oil. It sounds like you may have an ignition problem where the engine has a hard time firing until warmed. The blue smoke may be, at least in part, unspent fuel. I realize that a warm engine that uses oil will smoke blue, but excessively rich conditions on startup can result in a similar effect. If the choke circuit is delivering a little extra fuel from a dirty injector, the problem may be worse when starting from cold.
To remedy this, I would suggest a simple replacement of plugs and wires, as well as a fuel injector cleaner through the tank. I would bet money that these simple maintenance points would solve your problem.
