It froze up so I changed the filter and lost the prime. I did get the fuel back to the pump and to the injectors but now it will only run for a second then it shuts down. Any tips or tricks to get this thing going again.Thanks

I think the fuel is drawn from the tank, through a water seperator, and then into the filter by an electric fuel pump on that tractor. Any problems associated with bleeding are generally below the electric pump. Sometimes I have to fill the water seperator on my TS90. Once the main filter is full, the electric pump should charge the injection pump, and no further bleeding is necessary. Just listen to the pump load up, and then crank the engine. I have had some trouble with filters freezing at one time too, but once the water was out, no more trouble. HTH.

You must still have air in the fuel lines. Start by bleeding the filters, then the pump, then the injectors. Check your owners manual or shop manual for any special proceedures. Be careful not to run the battery down. Usually when I have a clear fuel line and have half the injectors showing all fuel and no air, it'll hit off and run. That what happens on my 4610.
