First replace the fuel, since if it takes a long time stopped, it can be deteriorated. Then replace the conmigible filter, as it can be clogged due to having been stopped so much time that the sediments have clogged them. Check that it comes to the Imjector pump, and that it leaves this with sufficient pressure, loosening the inlet tubes to the injectors, approved this same action to purge the fuel circuit (the broken injection pump can have). Check that the injectors' leftover tubes are not cracked, since it could take air out there, and put a good battery. If the transit is of electronic injection, disconnect the cables from the injectors to purge it, since these are very delicate.
