Yup, the Fiats are an absolute bear to get bled properly after they get air in the system. As cleon 159 said, bleed everything from the tank to the injectors, and you may have to do it more than once. You still may have to tow the tractor to get it started and then do the final bleeding once it is running. Good luck, and it does help to have a concrete wall close by to bang your head against.  <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt=":?" title="Confused" /><!-- s:? -->  I recommend running one out of fuel early in your ownership so you learn right off to never, ever run one of the Fiats out of fuel again! <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->
