Bobcat S205 controller shuts down engine starting after 4 seconds

[chrisras]

S205 diesel will not start. The controller will let the starter engage for about 3-4 seconds of starting, then it locks out the ignition switch until you shut it off and recycle the starting process. What is interesting about this is that I get no smoke or exhaust gas while it is cranking. I have switched the start relay with other ones and no change. Cleaned all battery terminals and connections and charged the battery. No change. Checked fuel flow out of the bleeder valve using the squeeze bulb. No air in the lines. Had a mechanic suggest to check lift pump flow and pressure ahead of fuel injection pump. I think that the fuel shut off solenoid is not opening. The. Code that registers is a 22-03 starter error off. Code will only show up after the controller stops the cranking the engine. If you cycle the power and look up the code it will say none. We drove this Skidsteer outside one morning and 4 hours later it would not start. We had a leaking radiator before this and I replaced the core after it would not start but fail to see how that would affect this starting problem. I have talked with other techs and no one can tell me why the controller is shutting off the starting process. They want me to bring the machine to them but that is more difficult as I will have to load it by picking it up with the payloader.

Did you ever find a solution to this, I’m now having an identical issue with my S300
